Abstract

Optimization techniques have so far been rarely used for structural-acoustic purposes. However, they are excellently suited for noise reduction of simple and large scale simulation models. The paper describes a general approach of utilizing optimization procedures in vehicle noise, vibration and harshness problems. We start with a review of structural-acoustic optimization. Then, the noise transfer function including structural harmonic analysis, acoustic influence coefficients and their coupling is described. This is followed by some remarks on the optimization process, discussing objective functions, useful design parameters and sensitivity analysis. Finally, two examples including a hat-shelf and a floor structure will be presented in the application section.
