摘要:

将魔术轮胎公式和主销间隙引入摆振模型,运用拉格朗日方法建立了非独立悬架汽车转向轮摆振的非线性数学模型。对比分析了有无主销间隙及不同转向结构参数和轮胎参数对摆振系统的影响。结果表明,主销间隙的存在使转向轮摆振系统的振幅明显增大,摆振发生的车速范围扩大,且使不敏感的参数对系统产生一定影响。

Abstract:

The tire magic formula and kingpin clearance were considered herein. A non-linear mathematical model of steering wheel shimmy with non-independent suspension was established by the Lagrange equation method. And the influences of kingpin's clearance and different parameters were analyzed. The simulation results indicate that the clearance of kingpin makes amplitude of steering wheel shimmy system increase, the speed range becomes larger, and the non-sensitive parameters may have an impact on the steering wheel shimmy.

Key words: steering wheel shimmy, clearance of kingpin, non-linear, numerical simulation
