Abstract

The interior noise in a vehicle can be reduced by optimizing the body panel thickness. A genetic algorithm was used to optimize the vehicle body panel thickness based on a coupled acoustic structure model of the vehicle body in HyperMesh. The Hammersley experimental design method was used to determine the response surfaces of the first-order global modal of the body-in-white, the body mass and the maximum sound pressure of a target point inside the vehicle. The maximum sound pressure at the target point was then used as the performance index in a genetic algorithm to optimize the vehicle body panel thickness. The optimum thickness reduced the maximum peak sound pressure at the target point by 4.0 dB. This algorithm gave 2.2% lower sound levels than a standard genetic algorithm, 2.2% lower than the global response search method, 2.3% lower than the adaptive response surface method and 2.5% lower than the feasible direction method, respectively. The results show that this genetic algorithm improves the stability and optimization ability of the genetic algorithm and this algorithm can efficiently optimize the vehicle body panel thickness.
