3-RPR平面并联机构正解的LINGO求解方法

Forward Solutions of the 3-RPR Planar Parallel Mechanism by LINGO Software Method

分析了3-RPR平面并联机构的求解模型,提出了用LINGO11.0软件求出全部解的方法:用LINGO11.0求出1个解后,将该解作为1个约束,使新解与该解不同,直至求出全部解.该法简单、实用,为实际机构的设计提供了多种选择方案,为机构学设计提供了全新的方法.

After analyzing the solution model of 3-RPR paralled mechanism, a new method is presented, which can find all solutions to mechanism synthesis and it is based on LINGO11. 0 software. A solution is found with LINGO11. 0,and the solution is used as a restriction. Then,to run the program again,the other one solution is found and so on. At last,all solutions are found. The problem of the 3-RPR planar parallel mechanism is solved by this method. This provides a simple realization method for mechanics design.
