| 摘 要： | 为建立系统仿真中运动单元的动态模型，首先根据仿真单元起始位置和终止位置的部分表面以及运动轨迹推导了包络面族的方程，然后根据包络面形成时与任意两个运动曲面的公切求取曲面族包络的瞬时接触线，为仿真干涉校验算法中计算各运动单元部件扫描体交集提供了理论依据。

| Abstract: | For construct the dynamic model of locomotion unit in system simulation, the equation of envelope surface set is deduced according to the original position, final position and the locomotion track. Then the instantaneous contact line of the envelope surface set according to the common tangent line between each locomotion surface when the envelope surface is formed. This algorithm is the foundation of interference check in system simulation for each locomotion unit. |
