摘　　要：本文首先通过对机载折叠机构做运动学分析,得出了曲柄的角速度和角加速度计算公式。在此基础上运用Pro/E对机载折叠机构进行运动学仿真,得出了曲柄的速度和加速度随时间变化的曲线。根据得到的运动轨迹,我们可以确定机载折叠机构是否存在干涉问题,从而有利于机载折叠机构的优化。In this paper , the kinematics simulation for airborne folding mechanism is firstly being made, and the formulas for calculating the crank＇ s angular velocity and angular acceleration are obtained. And then the Pro/E software is being used to simulate the movement of the mechanism, and the curves of crank＇s speed and acceleration of over time are then worked out. According to the motion tracks that have been obtained, the existence of interference problem can be judged, and then the mechanism can be optimized too.
