摘　　要：针对十字万向节传动轴激励导致的汽车振动噪声现象,通过激励—传递路径—响应的分析角度,探讨了从激励、传递路径到响应3方面优化十字万向节传动轴激励导致的汽车振动噪声问题的方法及分析流程,以一款4驱微车在4驱模式加速行驶工况下的方向盘共振现象为例,论述了上述流程在解决此类传动轴激励导致的方向盘共振现象的应用,并进行了前桥支撑刚度对前桥刚体模态和方向盘共振的灵敏度研究。The source-transfer path-response model is harnessed,regarding the propshaft with cross-type universal joint induced automobile noisevibration,to investigate the countermeasures and analysis process from the source,transfer path and response point of view,in the mean time,the issue of steering wheel resonance in a 4X4 mini van during acceleration in AWD mode is exemplified for applying the countermeasure and process to fix problems,as well as delving into the steering wheel resonance and front axle rigid body mode sensibility to front axle mount stiffness tuning.
