“Why we have to approach powertrain NVH from an overall vehicle perspective and across methods” was the topic of a presentation at the digital event simpulse day 2020given by Thomas Hofmann. Solving the challenges of NVH (Noise Vibration Harshness) in electric and hybrid powertrains means not only reducing or even eliminating undesired noise and vibration, but also achieving this goal in a cost- and weight-efficient manner. This requires various departments to collaborate more closely and different technologies to be combined. Thomas introduces the challenge and outlines a methodology as a solution, based on combining different simulation methods.
