摘　　要：对某型SUV高速行驶时方向盘摆振的问题进行研究,分析了振动原因,提出了一系列方案进行优化控制。试验结果表明:提高前下摆臂大轴套Y向损失系数和更换液压轴套,对方向盘行车摆振改善明显。为后续方向盘摆振问题提供积累,同时为汽车转向系统的研发设计提供了思路。The problem of steering wheel wobble during high-speed driving of an SUV is researched,the causes of vibration are analyzed,and a series of schemes are proposed for optimal control.The test results show that:increasing the Y-axis loss coefficient of the front axle arm bushing and replacing the hydraulic bushing can significantly improve the steering wheel driving vibration.Provide accumulation for subsequent steering wheel wobble problems,and provide ideas for the development and design of automotive steering systems.
