1.前言 车辆振动不仅与旅客的舒适度、对货物的影响、车辆的运行安全性有重要关系,而且影响到被运输机器的性能及车辆零部件的疲劳。 为了减轻振动,在理论研究的同时还需要做运行振动试验,记录振动的大小,判明 1. INTRODUCTION Vehicle vibration is not only related to the comfort of passengers, the impact on the goods, the operational safety of the vehicle, but also the performance of the transported machine and the fatigue of vehicle parts. In order to reduce the vibration, in the theoretical study also need to do running vibration test, record the size of the vibration, found that
