摘要
对目前汽车NVH性能有限元与试验分析进行了简要介绍。说明了有限元与试验分析的理论和基本内容。基于某车型白车身的有限元噪声传递函数分析与试验噪声传递函数分析对标,指出在试验与有限元分析过程中所要注意的问题。
The finite element analysis and test method of the vehicle NVH performance were introduced.The theory and basic contents of FEM and experiment were described.Based on the finite element transfer function analysis and experimental noise transfer function analysis of a white body,the problems to be paid attention in the test and finite element analysis were pointed out.
