摘要
为解决月球车在月球表面上的运动学问题,对月球车在非结构化环境下并且轮地之间存在滑移的情况下的运动学进行建模与分析。在分析多刚体链式机构运动的速度特性的基础上,建立整车速度的矢量表达式,利用矢量分析方法,建立摇臂悬架式月球车在崎岖地形中行进并且轮地之间存在滑转情况的运动学模型。利用ADAMS和MATLAB对运动控制过程进行仿真,验证该建模方法的正确性。
In order to solve the kinematics problem of lunar rover traversing over rough terrain, the kine- matics modeling and analysis of a rocker-bogie-mode lunar rover traversing uneven and soft terrain with slip are proposed. The vector expression of the lunar rover velocity is derived on the basis of the analysis of the ve- locity characteristics of a multi-rigid-body chain structure movement, and the kinematics modeling of a rocker-bogie lunar rover traversing over uneven terrain with slip is presented by means of the vector method of multi-body system. By using the software ADAMS and MATLAB,the simulations are implemeated and the validity of the modeling method is verified.
