摘要/Abstract

摘要： 基于ADAMS/Car建立了某微型轿车的4种不同结构的柔性拖曳臂后悬架模型，以及整车刚柔耦合虚拟样机模型进行了稳态回转道路试验，通过试验与仿真结果的对比，验证了整车模型的正确性。对不同结构的后悬架并进行运动学仿真，研究拖曳臂式后悬架结构改变对整车稳态回转性能的影响。对装有4种拖曳臂悬架的整车模型进行稳态回转仿真，结果表明:通过拖曳臂悬架的加强筋长度，来减小后悬架的侧倾角刚度，可以有效的改善整车稳态回转性能。

关键词: ADAMS/Car, 刚柔耦合, 拖曳臂, 稳态回转

Abstract: By applying the ADAMS /Car software，four types of flexible trailer arm rear suspensions and a rigid-flexible coupling virtual prototype model of mini car are established. Carrying out the steady turning test，the results of test and simulation are compared to verify the correctness of the whole vehicle model. The kinetic simulation of the rear suspensions of different structure are carried out and the effect of the change of the trailer arm suspension on the steady turning characteristics are studied. The simulation of steady turning characteristics is applied on the whole vehicle model on which four types of rear suspensions installs. The results show that the rolling angle stiffness of the rear suspensions will decrease by controlling the length of reinforcing rib of trailer arm，which will improve the steady turning characteristics efficiently.

Key words: ADAMS/Car, rigid-flexiblecoupling, twistbeamrearsuspension, steadyturningcharacteristics
