摘要:
利用Hypermesh建立某车声固耦合模型,在发动机激励下对车内噪声进行预测分析.利用板件贡献度分析得出峰值频率下贡献度大的板件,将其厚度作为设计变量.通过拉丁超立方试验设计,构造出质量和峰值频率下声压响应的响应面模型;通过Hammersley抽样对构造出的响应面进行误差分析,选出最优响应面模型.根据最优响应面模型以质量最小为目标,峰值声压、车身弯曲刚度和扭转刚度为约束条件进行遗传算法优化,并通过有限元模型验证了优化结果以及响应面法对提高车身优化效率的有效性,车冉噪声得到控制.
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.
