某车型高速行驶方向盘摆振分析

研究高速行驶方向盘摆振影响因素与测试方法。针对某款乘用车方向盘摆振的现象进行原因分析,通过对其进行道路再现试验,测试分析轮胎至方向盘的灵敏度,可知该车对轮胎异相位的激励非常灵敏;以副车架为参考点,建立模型,通过ODS分析进一步验证摆振产生原因。该研究为高速行驶方向盘摆振问题的解决提供依据。

Analysis on Steering Wheel Shimmy of a Vehicle at High-Speed

Study the influencing factors and test methods of steering wheel shimmy when driving at high-speed. The cause of the vibration of the steering wheel of a vehicle is analyzed, and the sensitivity of the tire to the steering wheel is tested by analyzing the road reproduction test. It can be seen that the vehicle is very sensitive to the tire’s out-of-phase excitation;the subframe is used as a reference, Established a model, and further verify the cause of the steering wheel shimmy through ODS analysis. This study provides the basis for solving the problem of steering wheel shimmy at high-speed.
