Noise Vibration and Harshness (NVH) performance is an important indicator used in the “Customer Satisfaction” category in the automotive industry. The powertrain, that is usually composed of the engine and the transmission, driveline, axle and exhaust subsystem, is one of the major sources of excitation in the vehicle, because it transmits vibration energy to the passenger compartment through structure-borne and air-borne paths. A V-model, that is cascading the overall performance of the vehicle down to the components, has been developed to break down the NVH performance. The aim of the analysis is to identify the components that have the dominant contribution regarding transferring noise and vibration in the passenger cavity.
