Exoskeleton Modeling Using MotionSolve & Activate

Presenter: Nino Michniok, Mechanical Engineering Student, University of Kaiserslautern

The first part of the presentation shows the detailed process of building the multibody system of an actuated exoskeleton in MotionView/MotionSolve (MV/MS). The required movements are transferred to the corresponding joints by “Motions”. By this the exoskeleton can Stand Up, Walk diagonally across the floor and Sit Down. In the second part the “Motions” in MV/MS are replaced by controllers (position control) whichdeliver a certain torque to actuate the exoskeleton. The main topic here is the implementation of the co-simulation between Activate and MV/MS. In the end the presentation gives a quick outlook of similar works at the University of Applied Sciences Kaiserslautern in Germany.

Vehicle Concept Design using Ride & Comfort Requirements for Truck & Trailer System Dynamics

Presenter: Kaustubh Deshpande, Chassis Engineer, Nikola Motor Company

This presentation describes Nikola Motor’s progression of design maturity from 1D CAE to 3D CAD/CAE for chassis system engineering work on their electric trucks. This progression spans from Voice of Customer to Functional Requirements to Functional Deployment to Structural Deployment. Nikola Motor starts with a ‘First Principles’ model of their truck/trailer vehicle dynamics, then they perform system modeling & simulation with Altair Activate using quarter- and half-truck/trailer models. Block diagrams are created using both signal-based blocks and physical-based blocks (with Modelica). Through this methodical process, Nikola Motor is able to derive more and better insight earlier in their development process regarding important vehicle characteristics for their trucks – ranging from ‘yaw rate of the tractor for loaded vs. unloaded trailer’ to ‘full-trailer load distribution sensitivity due to fifth wheel location’. Work is in-progress to tighten the connection between their 1D CAE simulations in Altair Activate™ and their 3D CAE multi-body dynamics simulations.

Heavy Equipment Simulations: Multi-body, Hydraulics & DEM

Presenter: Ronald Kett, Technical Specialist, Altair

For a Stewart-Gough-Platform (Hexapod), various software tools were used to study and design highly dynamic hydraulic drives together with an overall system control. Calculation of Eigenfrequencies, control design and comparison, hydraulic system design, and overall simulation control were done in Altair Activate, the mechanics of the Stewart-Gough-Platform was taken from a CAD model into Altair Inspire Motion. The co-simulation between control + hydraulics and mechanics was performed using Activate and Altair MotionSolve. Altair HyperView and HyperGraph were used to analyze and visualize the results. With the highly integrated solutions, the results could be achieved within a very short time. The different types of models (linear/simplified/full mechanics/hydraulics) made it possible to start with fast development cycles and finally achieve reliable results.

Real-Time Simulator of a Mobile Crane

Presenter: Arnold Free, Chief Innovation Officer and Co-Founder, CM Labs

Mechatronic systems and off-highway equipment design is rapidly evolving. With advanced control features, operator-assistance systems, and even full autonomy on the horizon, engineers are building complex systems simulation models to better understand their smart machines. Through the use of interactive and immersive VR software, systems models can be derived from high-fidelity engineering simulations and used for operator-in-the-loop, HIL, and SIL testing. Interactive virtual prototypes allow for human-factors test and measuring system performance in hyper-realistic virtual worksites. Simulation is also being used for AI based perception and motion planning in autonomous systems. Sales and marketing departments are now using interactive simulations and visualization to demonstrate products. The value of simulation is expanding rapidly in OEMs. CM Labs Simulations has recently partnered with Altair to bring together engineering simulation and interactive real-time systems models to perform all of the above. Validated multibody systems dynamics models from Altair MotionSolve can be used to build interactive models in Vortex Studio and combined with advanced real-time 3d graphics to create immersive live simulations with human interaction. With real-time simulation, it is also possible to connect to interactive control models and system level multidisciplinary simulations with Altair Activate. The presentation uses a mobile crane model as an example. It will demonstrate the process of translating the engineering models to real-time, creating realistic working scenarios and deploying in immersive simulators for operator in-the-loop testing and system demonstration.

Quadcopters: From System Modeling to Real-Time Simulator

Presenter: John Straetmans, Computer Engineering Student, University of Michigan

This project attempts to build an accurate real-time (RT) drone simulator through the full integration of a 1D functional model of a drone created in Altair Activate®, along with its corresponding geometry, into Unreal Engine via the Functional Mock-up Interface (FMI) standard. Then, VR, peripheral controllers, and other functionalities were added to the representation. This task was accomplished by modifying the Altair RT Vehicle Package, making it able to handle not just vehicles, but any system model located in an FMU for co-simulation, in this case a quadcopter model. Once the FMU containing the Altair Activate® drone model was successfully loaded into Unreal Engine, the tools provided by the application allow additional features to be added, such as VR support. By implementing an FMU, together with its geometry, into Unreal Engine, we can visually analyze the dynamics of the system to further verify the drone model and its performance. In the future, this integration process should be facilitated to automatically load any FMU following just a few steps.

Modelica Library for Real-Time Car Simulator

Presenter: Dario Mangoni, Engineering Professor, University of Parma

In the modern car industry, the advent of hybrid and electric vehicle systems is driving radical changes in the car electronics and software, demanding more and more advanced controlling techniques. Self-stopping, self-starting, ultimately self-driving cars are nowadays possible, because of the multitude of sensors, controller units and actuators making the vehicles “smart”. To simplify and make the interaction between the user and the machine more and more intuitive and user-friendly, a much broader and deeper investigation of different use scenario combined with the human interaction and intervention is critical. In this context, higher-detailed vehicle models are required to provide a valid prototyping tool which can be reliably used to test innovative controlling strategies, such as testing with the Man-In-the-Loop. The Car Real-Time Modelica library proposed here aims at providing a highly valuable tool for the vehicle control system design and test. The key competitive advantages in this approach are in the Maple model-based compiler for supporting high-level of details modeling; the adoption of the Modelica language which allows a transparent and physical approach to the modeling activities and finally the Activate platform which offers real-time capabilities within an environment meant for the signal-based control design. To graphically validate the library results, a visualization framework for realistic real-time simulations that assures high-fidelity scenario in which to test user experience was also realized.

System Simulation for HVAC

Presenter: Christian Kehrer, Altair [on behalf of Oliver Höfert, Simulation Engineer at Kampmann]

The increasing virtualization of engineering methods is inevitable. This also holds true for the design of systems that take care for the thermal well-being of humans, e.g. in buildings. If it comes to simulation of so-called HVAC (heating, ventilation, air conditioning) systems, very often high fidelity approaches like CFD are connected to it. In contrary, this contribution illustrates a 1D modeling approach of a heat exchanger in use of Altair Activate. The presentation explains the implementation of the NTU (Number of Transfer Units) method in a system simulation environment. This includes a short description of the approach itself as well as its current limits. Based on the implementation of a single cell, differing network configurations for the evaluation of use cases of varying complexity will be shown.

ROMs For Battery Cooling Systems

Presenter: Stefano Benanti, R&D materials engineer, Hutchinson

Battery cooling (BC) systems are frequently composed of several parallel branches, each leading to and away from a series of cooling plates. As a correct flow distribution in each branch and overall pressure drop are a key requirement from every customer, numerical computation is extremely important from the first stages of each project: the number of components and their dimensions have a relevant impact on the total cost and it is thus necessary to quickly provide results already in the Request for Quotation (RFQ) phase.The 3D computation of such cases, albeit feasible, takes a relevant amount of time and makes it more costly (both in terms of computational power and of necessary software licenses) to quickly provide results. The goal is then to develop a quicker method to provide results and allow for the necessary optimization cycles. Altair Activate® was chosen by Hutchinson to develop a library of ROMs representing different circuit components through which is possible to create 1D models able to respond quickly and precisely to such demands.

Integrated Systems Simulation from Requirements

Ed Wettlaufer, Technical Manager Mechatronics Group, Altair [on behalf of NAVAIR]

Government solicitations for proposals, or RFPs, for aircraft and airborne systems require preliminary designs with enough fidelity to accurately predict performance, in order to prove the design's ability to meet the Governments performance requirements. Modern high-performance computing provides the leverage to execute previously expensive analyses in areas such as computational fluid dynamics. The results of these high order analyses can be used to populate parameters in 1D systems models which can be easily coupled to medium order models from other disciplines. These capabilities allow the design engineer to rapidly iterate to levels of model maturity and accuracy not achievable years ago, resulting in high levels of confidence in the designs performance predictions in unprecedented time. Moving forward, Altair engineers will employ Multiphysics and co-simulation to execute the Engineering and Manufacturing Development phase (EMD) for one subsystem of the preliminary design developed in the afore mentioned pre-acquisition phase.

Multi-Fidelity E-Motor Drive Solution

Presenters: Ulrich Marl, Key Account Manager for Electric Vehicle Motor-Feedback Systems, Lenord+Bauer & Andy Dyer, MBD Sr Technical Specialist, Altair

This presentation shows a modeling process to quantify the position/speed sensor (e.g, encoder) effects on an e-motor, and corresponding control system for a concept traction motor similar to the Nissan Leaf. The integrated solution of the e-drive is carried in Altair Activate as a system builder, using other Altair solutions e-motor solutions in FluxMotor and Flux to generate data for the e-motor itself, as well as the optimal current values for the Field-Oriented Contoller. The inverter is driven with efficient space vector pulse width modulation. The integrated solution also supports different levels of modeling fidelity for the system components, for example for the e-motor where either direct co-simulation with Flux for detailed finite element analysis or a reduced order model (ROM) using look-up tables. In this way, sensor design parameters can be evaluated within an accurate system of the e-drive to improve performance and efficiency.

Solving Challenges in Electric Motor Design

Presenter: Berker Bilgin, Assistant Professor of Engineering (ECE) at McMaster University and co-founder of Enedym Inc.

Electric motors in general, are made of certain parts, such as the stator, rotor, coils and magnets, and mechanical parts. These parts might look simple and bulky from the outside, however, the highly interrelated relationship between the geometry of these parts, characteristics of materials, and the way the current is controlled, defines the cost, size, efficiency, performance, and lifetime of the motor. In electric motor design, multidisciplinary aspects are highly interrelated. The effect of various parameters on the electromagnetic, thermal, and structural performance should be investigated together to come up with an optimized design. This is possible by developing the platforms where the multidisciplinary aspects are modeled in a software environment, as we are doing with Altair software.

Internal Noise Simulation/Emulation

Presenters: Rafael Morais Cunha, CAE Engineer in NVH, FCA Group & Frederico Luiz de Carvalho Moura, NVH CAE Leader, FCA Group

To make the driving experience more comfortable for passengers inside a vehicle compartment, in an increasingly shorter development cycle, predictive methods for the acoustic response characterization are used by vehicle engineering teams. The main purpose is to estimate the sound field in the car cabin. The FCA NVH team identified in Altair tools an excellent opportunity to develop a complete solution for acoustics simulation. Supported by the Altair technical team, new methodology was created to convert frequency domain analysis into actual sound waves. This method was used to study the NVH steady-state acoustic performances. And development is in progress to simulate an acoustic environment to reproduce all vehicle noises in operational condition. Using this methodology, it’s possible to virtually understand the acoustic behavior of vehicles, helping to make decisions in early design stages which could save design cost, time and also improve the driving experience for passengers.

Transient Analysis of Switched-Reluctance Motor Drive by FE Model Co-Simulation

Presentation by Lino Di Leonardo, University of L'Aquila.

This presentation showcases an analysis technique of electric motor drive based on transient simulation tools and embedded finite element motor modeling (co-simulation). A couple of software tools, Altair Flux and Activate, are employed suitably interfaced each other. The first one allows the computation of the motor electromagnetic behavior using a finite element model, while the second one allows the dynamic simulation of the control and feeding converter. The interacting use of these tools allows a detailed prediction of the motor transient behavior under a given control strategy and drive scheme. As test case a multi-phase Switched Reluctance motor for aerospace application is considered.

The results demonstrate that the co-simulation procedure allows taking into account not negligible phenomena, such as dynamic torque ripple, usually not considered in similar studies. Hence, co-simulation analysis represents a significant step for the integrate design of the motor and control, as well as a meaningful tool for electrical drives education.

EV Thermal Analysis: 1D and 3D Model Integration for Cockpit and Batteries

Presentation by Massimiliana Carello, from Beond & Politecnico di Torino.

Nowadays automotive climate control systems are evolving at a rapid pace to meet the overall vehicle requirements. System evaluation is one of the major requests currently faced by the automotive manufacturers and their suppliers. Thermal comfort, convenience and range are equally important user expectations, even if they may represent “opposed” performance for a modern EV, especially in an urban driving cycle.

In this framework, to achieve the expected targets and limiting the time-to-market and costs, a complete vehicle thermal model is to be developed to evaluate the cockpit thermal request for occupants' comfort at different ambient temperatures as well as solar radiation. Furthermore, the battery thermal management is to be investigated, to avoid cells damages and deterioration. The aim of this technical presentation is to highlight the integration capabilities of a lumped parameters model (1D) developed with Altair Activate for fast simulations and a CFD model (3D) of the battery liquid cooling system developed in AcuSolve. The Models realized are validated using experimental data.

Aspects of Heterogeneous System Models in Industrial Applications

Presentation by Robert Höpler, Founder of SysOpt GmbH.

Heterogeneity can be present on various stages in system modelling and simulation. A system model is often called ‘multi-domain’, when different technical domains are present, such as hydraulics, mechanics, and control. When it comes to simulation this is just the surface of this domain level. Various mathematical and modelling formalisms can lie underneath which lead to different mathematical equations of motion, numerical properties, and computational complexity. On a specification level we see the choice between different modelling formalisms and modelling languages, libraries, coding styles, and authoring tools. Often there is a need to mix these. Decisions taken here strongly influence expressiveness of the models and ability for code generation and deeply impact software engineering topics such as development processes and exchange of models. Multi-domain approaches such as Modelica try to reconcile some these sources of heterogeneity. On an executional level we find classical desktop system simulation but more complex settings such as co-simulation, parallelization, real-time systems, and optimization which constrain numerical stability and precision and simulation speed. There might be an intricate feedback to the specification level, e.g., when modelling for specific solvers. Efforts like the Functional Mockup Interface (FMI) address some of these aspects and focus on interfacing and exchange of executional models. Prevalent system simulation tools are usually mature and controllable – as long as one stays within the desired scope of the tool. Following some examples we show how practical considerations influence design decisions and the choice of tooling.

The mathematical models of the gas turbine and the generator are based on physical principles, such as mass and energy conservation, as well as on correlations from the literature, including heat transfer coefficients and tables of thermodynamic properties. The models have been developed and tested in native languages (Fortran 90 and C++) and their integration with Altair Activate is achieved through the Custom C Block functionality. The system is first tested in Activate in a base load scenario, being then subjected to load changes. This work discusses the test results and shows the advantages of using sT Activate in the simulation of thermal and electrical phenomena.

Fast and Reliable Software Interfaces to Speed up the Design of Electric Motors

Presentation by Luigi Rizzi, Technical Director at SPIN Applicazioni Magnetiche.

The car industry is undergoing an unprecedented shift, between electrification, car sharing and autonomous drive. Car makers are going to roll out several zero-emission models in the next few years and their engineering departments are going to face new challenges. Engineering methodologies and good-design practices related to the well-known internal combustion engine must be reviewed and adapted to the electric propulsion system, considering multi-physic analyses in order to cover the various aspects of the vehicle performance. In this presentation a fast and reliable solution for the design of electric motors is shown.

A powerful software interface has been prepared in order to help the engineers to setup the model, define targets and boundary conditions, include multi-disciplinary verifications and collect analyses results. Using this tool, designers can easily and quickly perform electromagnetic analysis with the Altair software for electromagnetics, Flux, verify the performance in terms of delivered power, torque, losses and efficiency, check the thermal behaviour by means of equivalent thermal networks built in Activate and at the same time verify the stress levels and the NVH performance with OptiStruct, in order to define the early stage details of the product development. Activate plays a key role to speed-up the analysis because allows to obtain fast and accurate thermal information reducing the time usually required to simulate this domain.

Virtual Tryout - Digitalization for an Efficient Commissioning of Forming Tools

Presentation by Dr. Lars Penter, Head of Machine Technology at University of Dresden.

The life cycle of a forming tool consists of five major phases. It starts with the process and tool design followed by its assembly, the ramp-up and serial as well as spare part production. Due to every increasing system complexities, various simulation tools accompany today’s tool life cycle. A popular term in the current world of production is the “Digital twin”. It is a simulation model, which contains at least two sub-models of different physical disciplines, connects different time scales and regularly synchronizes data with the real system. Such a model must be a highly accurate white box model.The presentation will address the generation of a virtual twin on the example of the virtual try-out of forming tools. The simulation model employs RADIOSS (for forming process simulation), MotionSolve (for multi-body simulation of machine mechanics) or Activate (for more complex multi-domain modelling of mechanics, hydraulics and electrical components). Currently, the digital twin allows for computing the interactions between forming process and die cushion. This enables the calculation of correlations between die-cushion cylinder forces and flange draw-in. The presentation shows how optimizing these cylinder forces in HyperStudy benefits the final part quality and shortens real tool try-out time.

Bridging the Gap Between Requirements and Analysis using ModelCenter with Altair Activate

Presentation by Ilya Tolchinsky, Phoenix Integration.

Phoenix Integration is a recently added member of the Altair Partner Alliance. Its product ModelCenter can create complex, fully automated simulation workflows and link these against Model Based Systems Engineering (MBSE) models. These typically descriptive models can now include accurate prediction of the system performance. This means that the status of the system requirements can be verified early in the product design cycle helping to avoid costly mistakes. Using ModelCenter the systems engineer can explore the possible design options and choose a configuration that represents best value while meeting its requirements. This paper explores this way of working by using an example built around an Activate Anti-lock Braking System (ABS) model. The example includes a SysML model built in Cameo Systems Modeler. It is connected to a number of analyses that evaluate the performance of a braking system. The paper illustrates the details of the architecture for this integration. ModelCenter design exploration techniques are then used to find the optimal configuration.

The Design Revolution Offered by Combining Additive Manufacturing with Simulation Driven Design

Topology optimization is a computer based calculation procedure which can design mechanically stressed component structures in such a way that the highest possible rigidity can be achieved with minimal material usage. Only those parts of a component which are essential for the required flux of force and necessary stability are generated. This results in complex structures which can only be built partially or not at all using conventional production processes. At this point the advantages of additive manufacturing come into focus.

An Interview with Ben Farmer of Robot Bike Co. Discussing the Development of their R160 Bike with Altair

Robot Bike Company (RBC) is a new startup established in the UK by aerospace engineers and mountain biking enthusiasts who identified the potential of combining additive manufacturing technologies with carbon fiber to, in their own words, “create the best bike frames possible”. To deliver a customizable, lightweight, high strength bike, RBC’s frame was intended to be created from carbon fiber, a material very common in the industry. The carbon fiber tubes, as well as the bike’s other components and systems were to be joined by additively manufactured titanium ‘nodes’, manufactured based on the specification of individual riders. Altair ProductDesign’s engineering team was tasked with optimizing these joints, which included the head tube, seat post and chain stay lugs, to ensure they were as lightweight as possible and still able to withstand the forces of downhill mountain bike riding, all while being fit for the AM process.
