Abstract
This paper discusses issues related to the successful application of the finite element method (FEM) and an experimental modeling approach to automotive structure-borne noise and vibration control problems, as excited by powertrain and tire - road interaction sources from 100 Hz to 1 kHz. In this range, the system dynamics are influenced significantly by higher-order modes of the car body and its interior acoustics. Given the complexity of the overall problem, a new formulation that combines the FEM and measured frequency response spectra is suggested to model coupled powertrain - chassis-body systems. Salient features including limitations are discussed and the results for two practical noise control cases are presented here.
