NVH Prediction in Electric Powertrains: Considering Inverter and Motor Spatial Harmonics


Much time and consideration from automotive engineers goes into analysis of noise, vibration, and harshness (NVH) since consumers expect their vehicles to provide as quiet and smooth a ride as possible. Modern technological advancements provide a multitude of opportunities to maximize design success in this area. In this 30-minute Webinar, industry experts will demonstrate a multi-physics workflow for capturing the NVH coming from electric powertrains. This includes electromagnetic, electrical, mechanical, and acoustic modeling to capture the effects of spatial harmonics of the traction motor, harmonics of the inverter and its controls, and bearing and housing design on acoustic performance of electric powertrains.
