客车驱动桥振动与噪声研究

Study on the Vibration and Noise of Passenger Car Drive Axle

驱动桥是客车动力传动系统的重要环节,其振动、噪声水平对整车NVH性能的影响至关重要。文章通过驱动桥振动噪声机理研究,并结合噪声故障测试分析,得出了导致驱动桥噪声问题的根本原因。最后,根据研究结果提出相应的处理方案并有效地解决了噪声故障。

Drive axle is the important participation of the drive train for passenger car, its vibration noise level affect the entirety NVH performance.This paper findout the primary reason of drive axle noise by vibration noise theory research and test of drive axle. Finally, solve the noise fault based on the research conclusion.
