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.

Multi-body Enhancements & Customer Successes
Presenter: Rajiv Rampalli, Sr VP in HyperWorks Core Development team, Altair


Altair’s products for multi-body system simulation (MBS) – MotionView, MotionSolve, and Inspire Motion – form a key component of multi-disciplinary system simulations. In this presentation, we will look back on several achievements this year, in the form of customer successes as well as recent enhancements to these products which significantly extend the depth and breadth of capabilities.

Some of these application examples also involve connections from MBS to other Altair technology or to 3rd-party technology such as to Altair OptiStruct (for flexible bodies and light-weighting) and Altair Activate (for hydraulics) and EDEM (for discrete element modeling of bulk materials).


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.

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.

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.
