摘要

以某履带车辆悬挂系统为例，利用动力学软件RecurDyn建立单轮动力学模型。基于车辆动力学与冲击碰撞原理，研究油气弹簧与液压缓冲器对悬挂系统性能影响及车体行驶过程中悬挂系统缓冲、吸振性能。结果表明，车辆单轮悬挂模型及动力学仿真具有简单、可靠、快速等特点，可一定程度上替代整车仿真。油气弹簧与液压缓冲器组成的悬挂系统有非线性、变阻尼特性，在大振幅激励下减振效果更明显。

Abstract

For studying the performance of hydro-pneumatic spring and hydraulic buffer and their effect on a suspension system, the dynamics model of single-wheel suspension system of a tracked vehicle was established by RecurDyn. Based on the vehicle dynamic and the crash theory, the cushioning and absorbing of the crash energy of the suspension system were studied. The results show that a dynamics model of single-wheel suspension system used for simulating is valuable for studying the properties of the suspension system, which can replace a whole vehicle’s simulation to some extent. The hydro-pneumatic suspension system has non-linear and large damping properties which have a strong ability to cushion and absorb the crash energy in a large amplitude vibration.
