Lighter. More efficient. Electrified. Those are the key aspirations of almost every car manufacturer today. The urgent necessity to reduce our carbon footprint is leading to a burst of innovation. New materials and manufacturing methods as well as complex multiphysics technologies grab all the attention. They radically change how vehicles are developed. Can engineers working on classic performance requirements such as noise, vibration and harshness (NVH) keep up?
Reducing weight limits NVH engineers in their margin of maneuver. At the same time, more efficient internal combustion engines require higher combustion pressure, which is detrimental for NVH. And powertrain electrification with E-motors and gearboxes leads to mid- to high-frequency noise in the cabin, both structure- and airborne. So how can NVH engineers effectively deal with these challenges?
