摘要
给出了任意正交坐标系下的速度矩阵法推导和动力学方程普遍表达式,将速度矩阵表示的动力学方程组转化为计算机可运算的格式,实现了在未写出方程表达式的情况下可直接求数值解的目标。
The paper establishes formulas of velocity matrix and expressions of dynamics equation group in arbitrarily coordinate system. Dynamics equation group expressed by velocity matrix is translated into a format operative in compute, by which directly calculation of numerical value is realized in the ease of no equation expressions.
