研究空间对接机构差动式缓冲阻尼系统受轴向力偶作用时的运动学和动力学 ,找出捕获环角速度与丝杠沿其轴线平动速度的精确关系式 ,导出系统运动约束方程和动力学方程 。

Presented is an analysis of the kinematics and dynamics of the differentially mechano-electronic spring-damper system subjected to a couple about its axis of symmetry, which is applied in a spacial butt mechanism. The exact relation between the angular velocity of capture ring and the translation velocity of screw bar directed along its axis is found out. The motion constraint equations and dynamics equations are deduced, and the analytical solutions of the simplified equations are given.
