摘　　要：随着客户对产品舒适性要求的不断提升,发动机NVH性能的关注度日益提升。本文介绍了某汽油机正时异响的CAE分析、设计和试验协同优化过程,展示发动机NVH设计、CAE分析与试验测试协同合作的作用。With the increasing requirement on comfort by customers, more and more attentions are paid to engine NVH. In this paper, CAE analysis, as well as design and experimental optimization of abnormal noise of a gasoline engine timing drive system are discussed, and the effectiveness of using NVH design, CAE analysis and testing collectively is demonstrated.
