Abstract
The overall impression that a vehicle creates is strongly influenced by its acoustic behaviour. In addition to the various excitation mechanisms, the transfer behaviour of the body in particular has a critical influence on the character of the interior noise. During the vehicle development process, key decisions need to be taken with regard to the vehicle body before the first prototypes exist as hardware. To support this process, a virtual noise prediction system has been developed at FEV that combines the established experimental method of interior noise simulation with an FE calculation for the vehicle body.
