摘要

车辆转向机构中各间隙运动副之间的动力学耦合会对其动力学响应产生重要影响。以考虑转向机构中间隙运动副耦合作用的非独立悬架车辆为例，基于分析力学建立了六自由度车辆摆振分析模型。应用数值方法分析了车辆摆振系统的动力学响应特性，对其中出现的Naimark-Sacker分岔、混沌等现象做了分析，并从能量传递角度对其摆振机理进行了解释，相关分析结论可为更好地实现车辆摆振控制提供理论支持。

Abstract

Dynamic coupling between movement pairs with clearance in steering mechanism of the vehicle can make great influence on its dynamic response. Based on analytical mechanics, a 6-DOF dynamic model of vehicle shimmy system with consideration of dynamic coupling between two movement pairs with clearance is established. Numerical analysis is carried out to evaluate the dynamic response of vehicle shimmy system. Some phenomenon such as Naimark-Sacker bifurcation and chaos for the system are discussed, and the dynamic mechanism for vehicle shimmy is investigated in view of energy transfer. The conclusions can provide theoretical basis for attenuation of vehicle shimmy.
