摘要
为解决某履带车辆水泥路面行驶时的振动问题,测试了该车及变型车的振动特性,并以假定的激励建立了车速与车体周期振动频率公式,此公式获得的计算结果与测试曲线的基频基本一致,验证了激励假定的正确性.提出了3种关于主动轮设计的减振方案.
In order to solve the vibration problem of a tracked vehicle on flat hard road, the vibration characteristics about the vehicle and its variant vehicles have been tested, and the formula about the vehicle speed and its hull＇ s vibration frequency has been derived based on an assumed excitation. The calculating results obtained from the formula were coincided with testing ones of acceleration PSD, verifying the correctness of the assumed excitation. Three solutions of vibration reduction on the sprocket design have been proposed.
