- Abstract:
- A coupled structure-acoustic model of the car was built by hypermesh.Considering the excitation of the engine,prediction and analysis of the car inner noise were conducted.Using analysis of panel contribution,the key panels were found at peak frequencies and set these panel thickness as design variables.The response surfaces of mass and acoustic responses at peak frequencies were built by Latin Hypercube Sampling and error analysis was done based on Hammersley Sampling in order to select optimal response surfaces.Using selected response surfaces,mass as objectives,acoustic responses and vehicle stiffness as constraints,the optimization based on genetic algorithm was carried out.The effectiveness of the optimization result and improvement of optimization efficiency by response surface method were validated by the finite element model and the vehicle inner noise was improved.
