摘要
以某型混合动力轿车起步加速过程中抖动噪声问题为研究对象,通过实车测试、模态试验以及虚拟分析等多种手段,对问题振动来源和传递路径进行了系统分析,最终确定对相关结构件进行整改,有效改善了抖动性能,解决了振动噪声问题。为新能源汽车整车NVH性能的开发与设计提供了新的方向。
One sort of hybrid auto is studied on NVH problem in acceleration process. By vehicle test, modal test and simulation, analysis is done to find the rootcause and translate path. Relative structure is modified to improve this NVH problem. A fresh way to improve hybrid auto NVH performance is provided.
