Squeak and Rattle Prevention - Why You Should Not Wait for Your First Prototype

Dr. Royston Jones, Global CTO, Altair Consultancy, discusses how the global pandemic has been a catalyst for companies to harness the potential of simulation by reconfiguring their established design processes and traditional organizational structures. Technologies and methods that can deliver design feedback at the speed of development are already available; reducing expensive physical testing while injecting innovation into a company’s product. The rapid evolution towards a connected everything is having a huge effect on design. From autonomous and electric mobility to smart consumer products with new business models, development teams must now integrate simulations of controls systems into complex multi-physics models enriched by data captured by sensors in the field. Especially during concept development when rapid exploration of design ideas is essential, a full embrace of simulation will be essential to compete. The recording is about 19 minutes long, and was presented at the 2020 Global Altair Technology conference.

Achieving the targeted brand image in a short development cycle time with minimal or zero prototypes is a major challenge faced by EV companies. To overcome this challenge, Altair, HBK and Romax have jointly developed a simulation driven process coupled with capabilities to virtually experience the noise and vibration characteristics, giving engineers a way to obtain real time performance feedbacks as the vehicle is being developed. This joint presentation on the proposed NVH development process covers a wide range of topics, including benchmarking, target setting, full vehicle and motor gearbox simulation loadcases, troubleshooting, optimization and stochastic analysis, and playback of simulation results for subjective evaluations, with a number of new technologies representing the global best practice in sound and vibration design and development. Join us to explore ways to control the sound and vibration characteristics of the vehicle, achieve the right sound, and avoid common NVH pitfalls, while accelerating time to market utilizing and experiencing virtual NVH prototypes.
