摘要/Abstract

摘要： 在崎岖路面上行驶的车辆由于轮荷的不均匀性，车身承受着较大的扭转荷载．为减小扭转荷载，文中提出了一种新型消扭悬架结构，通过建立简单的数学模型介绍了其消扭原理，并利甩多体动力学仿真软件ADAMS建立了装备有该消扭悬架的车辆模型，在不同的车辆行驶速度下对其消扭能力和接地性能进行了仿真．结果表明，在车辆低速行驶条件下，该消扭悬架减小车身扭转荷载的效果较为明显，车辆的接地性能比常规悬架有较大提高．

关键词: 消扭悬架, ADAMS 扭转荷载, 接地性

Abstract:

A vehicle body may bear a large twist load due to the uneven load on four wheels when the vehicle runs on rough road. In order to reduce the twist load, a new type of torsion-eliminated suspension structure is brought forward, and a simple mathematical model is established to explain the principle of torsion elimination. Moreover, a model of the vehicle with the suspension is constructed by using the multi-body dynamics simulation software ADAMS, and the abilities of torsion elimination and ground adhesion of the vehicle at various speeds are simulated. The results show that, when the vehicle runs at a low speed, the torsion-eliminated suspension is effective in reducing the twist load of vehicle body and in improving the ability of ground adhesion.

Key words: torsion-eliminated suspension, ADAMS, twist load, ground adhesion ability
