摘要

提出一种平面并联机器人工作空间新的表达方法。以3RRR平面并联机器人为例,采用迭代搜索法,以运动方程逆解为判别式,进行工作空间的圆周式搜索,得到了全姿态工作空间的三维展示,并对其特性进行研究。在此基础上,得到可达工作空间以及工作空间不存在空洞的杆长配比。

Abstract

A new representation method of the workspace of a planar parallel manipulator is presented.Taking the 3 RRR plane parallel robot as an example,according to the iterative search method,the inverse solution equation is used as the discriminant,and the circular search of workspace is carried out. After the data processing,the three-dimensional display of the full-posture workspace of planar parallel manipulator is obtained,and its characteristics are studied. On this basis,the reachable workspace is obtained and the working space does not exist empty pole length ratio.
