考虑齿轮—齿条转向器侧隙的汽车摆振系统动力学建模及分析

摘要

基于非线性系统动力学相关理论,建立考虑侧隙的齿轮—齿条传动副动力学模型,并以此为基础建立齿轮—齿条传动副侧隙的汽车摆振系统动力学模型,通过数值算例分析了齿轮—齿条传动副侧隙对汽车摆振系统动力学行为的影响,相关方法和结论有助于更好地实现汽车摆振控制.%Based on nonlinear dynamics theories,a dynamic model of rack-and -pinion movement pair was discussed,and the dynamics model of vehicle shimmy system with consideration of rack - and - pinion movement pair backlash was presented. The dynamics behavior of the system was analyzed by numerical examples,which provides theoretical basis for better vehicle shimmy control.
