摘　　要：研究了推力钢带式和链条式无级变速器的振动噪音特性。对其中的链式无级变速器设计了降噪方案,并进行了噪声优化研究。结果表明:在对钢带和链条无任何降噪措施的前提下,推力钢带式无级变速器噪声水平明显优于链式无级变速器,但在链式无级变速器链条上安装降噪导板后,链式无级变速器整体噪声得到大幅下降,与推力钢带式无级变速器噪声水平接近。This thesis investigated the NVH performance of the push belt CVT and chain CVT. Based on the study of the two types CVT technology,we designed the NVH optimizing solutions,especially for the chain CVT technology. As a result： without any special solutions for the NVH performance of chain CVT,the push belt CVT＇s NVH performance is much better than chain CVT ＇s. But after applying a special guider on the chain CVT,the NVH performance of the chain CVT is largely improved and is comparable to the push belt CVT.
