Seamless integration of 0D-1D and 3D worlds
This webinar will introduce you to Altair Activate for control system design and the ease of solving real world problems with co-simulation between MotionSolve (multibody simulation suite) and Activate.

Simulating the Suspension Response of a High Performance Sports Car
The use of CAE software tools as part of the design process for mechanical systems in the automotive industry is now commonplace. This paper highlights the use of Altair HyperWorks to assess and then optimize the performance of a McLaren Automotive front suspension system. The tools MotionView and MotionSolve are used to build the model and then carry out initial assessments of kinematics and compliance characteristics. Altair HyperStudy is then used to optimize the position of the geometric hard points and compliant bush rates in order to meet desired suspension targets. The application of this technology to front suspension design enables McLaren Automotive to dramatically reduce development time.

The Use of MBD Modelling Techniques in the Design and Development of a Suspension System
This paper describes the use of Multi-body Dynamics (MBD) modelling techniques in the design and development of a suspension system for a novel autonomous vehicle. The general approach and philosophy is described, whereby MBD techniques are used in conjunction with an independent (parametric) whole vehicle handling simulation. This is supplemented with examples, showing how MotionSolve was used (in tandem with CarSim) to develop the suspension elasto-kinematic geometric properties to meet specific cascaded targets, to optimise a weighing strategy, to predict forces under a variety of quasi-static and dynamic loads, and to estimate response to track inputs.

Cooper Standard Speeds Development of Next-Generation Pumps with Altair’s AcuSolve CFD Solver
With more than 22,000 employees in
19 countries, Cooper Standard supplies the vehicle industry with fluid delivery systems, sealing and exterior systems, thermal and emission systems and AVS. The company’s Electromechanical Department is an advanced research and development arm of the Cooper Standard North America division. It’s goal is to marry mechanical systems with electronic controls. This new technology improves overall vehicle efficiency by providing on-demand fluid delivery and by eliminating the power loses inherent in conventional systems.
In designing new pumps for this type of system, CAE Engineer Tom Lincoln uses computational fluid dynamics (CFD) software to simulate the flow of coolant through the device. He and his team began using CFD computer-aided engineering tools as long ago as 2003, and computer simulations have become an essential part of his organization’s product development process.

Addressing Design Development Challenges Through Simulation Driven Platform
Automotive suppliers are facing many challenges in having in-house simulation capabilities compared to that of OEM’s. One of the ways to overcome these challenges is to invest in simulation technologies that require an affordable initial investment, the ownership cost of which is low, the codes are reliable & proven, and the suite of tools provide suppliers access to a broad range of solvers (a true multi-physics environment) helping them pick and choose the solvers as per their simulation requirements. In the early stage of in-house simulation implementation at Endurance Technologies, HyperWorks was being adopted primarily for pre and post processing due to its extraordinary FE modeling solutions. With constant support, Altair team has helped Endurance in exploring and implementing various HyperWorks solvers at Endurance Technologies.

ADAS Simulation Under Severe Vibrations
Automotive radars are becoming standard equipment on vehicles. Their purpose is to adjust the distance between vehicles and/or alert the driver when dangerous situations arise. Several antenna architectures are used to cover the different safety functions in complex bumper/car chassis environment where the side
effects become more and more significant on the radar performances. Hence, automotive radar integration process becomes a very important
topic. Weak radar integration will generate gain loss, high side lobes levels and angular errors. Those degradations will impact the radar range,
the main radar axis (BSE) and the radar detection quality (resolution, ambiguity, discrimination).
