摘　　要：为解决全方位轮式移动机器人搭载传统悬挂装置越障行驶时,轮距变化和轮毂中心面侧倾导致机器人运动控制难度大等问题,设计了一款由平行四边形机构、偏置曲柄滑块机构和摆动摇杆机构组成的多连杆式悬挂装置。通过ADAMS软件进行了不同地形环境的动力学仿真分析与优化设计,确定了最佳连杆结构参数。实物样机试验表明,机器人越障行驶过程中的操控性能以及轮子着地性与运动精度得到提高。In order to solve the existed problems of difficulty in motion control for robots such as track width changes and variety range of camber increases when wheeled mobile robots equipped with conventional suspension surmounted obstacles,a novel independent linkage which was made up of parallel crank mechanisms,offset slider crank mechanisms,and oscillating guide bar mechanisms was designed.Dynamics simulations and analyses were carried out in different terrains with the software ADAMS,and the optimal length of each link was determined.Experiments of robot verified the improvement of controllability,landing ability of the wheels,and the accuracy of robot motions on obstacle surmounting.
