摘　　要：针对车辆在粗糙路面行驶时及传统车辆在加速过程中存在的方向盘抖动问题,采用方向盘动力吸振器是行之有效的解决方案。文章通过振动传递、转向管柱模态等方面的实车试验对比,证明了方向盘动力吸振器对改善方向盘抖动问题具有显著效果。同时,通过对比不同频率动力吸振器的改善效果,为方向盘动力吸振器调试提供参考。Aiming at the problem of steering wheel vibration when the vehicles drive on the rough road,the steering wheel dynamic vibration absorber is an effective solution.In this paper,through the comparison of vibration transmission,steering column mode and other aspects of the vehicle,the steering wheel dynamic vibration absorber is proved to have a significant effect on the steering wheel vibration.At the same time,by comparing the improvement effect of different frequency dynamic vibration absorbers,a reference for the debugging of steering wheel dynamic vibration absorption is provided.
