| 摘 要： | 针对东风EQ2102型独立悬架越野汽车的前轮摆振问题进行了道路试验分析,研究了前轮失衡量、转向系统阻尼和刚度对前轮摆振的影响。试验及分析表明,该车摆振主要为强迫振动,通过控制激振源、增大转向系统阻尼可抑制摆振。提出了采用阻尼轴承代替主销滚针轴承来增大转向阻尼的解决方案,同时评估了阻尼轴承对汽车操纵稳定性的影响。

| Abstract: | Based on the front wheel shimmy of EQ2102 independent suspension off-road vehicle,the road tests are carried out and the influence of the wheel imbalance,steering system damping and stiffness on the front wheel shimmy is studied.The test and analysis show that the shimmy is a forced vibration and can be restrained by controlling excitation source and increasing steering system damping.We present the resolution method by replacing needle bearing with damping bearing in order to add steering system damping,at the same time,the influence of damping bearing on vehicle handling stability is evaluated. |
