摘要

采用隐式积分法求解了机械臂仿真中出现的一组混合微分方程和代数方程。通过对矩阵雅可比矩阵的特殊结构的探索,可以将离散自由度方程的维数简化为若干个自由度。独立和相关的广义坐标直接由系统拓扑确定。以6-R机械臂为例进行了仿真。

Computational scheme for simulating robot manipulators
A set of mixed differential and algebraic equations (DAEs) which arises in the simulation of a robot manipulator is solved simultaneously using implicit integration. The dimension of the DAEs which have to be solved by LU factorization at each integration step can be reduced to the number of degrees of freedom by exploring the special structure of the Jacobian matrix of DAEs. The independent and dependent generalized coordinates are determined directly from the system topology. The simulation of a 6-R manipulator is given as an example.
