| 摘 要： | 提出一种空间连杆机构位置分析的新方法。首先，利用假设的开链机构实现了机构结构尺寸参数的描述与存储，再用闭链装配的数学条件直接建立位置分析矩阵方程，从而实现了对矩阵方程的直接推导并求解出位移输出量。实际的算例显示了这是一个系统和实用性都很强的方法，特别适用于计算机上运动分析算法的实现。

| Abstract: | A new approach to spatial linkage position
analysis is presented in this paper.First,the convenient method is used to describe and
store linkage's dimensional parameters by means of the supposed open chain.Then matrix
equations about the position analysis are given according to the mathematical conditions
of closed chain assembly,so that the output positions can be deduced directly from above
equations.This approach proves to be systematical,practical and the better one for
realizing the algorithm of the kinematic analysis with computers. |
