基于3-PRRR并联机构的3T对称耦合机构的构型综合
Type Synthesis of 3T Symmetric Coupling Mechanisms Based on a 3-PRRR Parallel Mechanism
摘要
Abstract
Based on a 3-PRRR symmetric parallel mechanism,3T symmetrical coupling models with the primary node are summed up as two types by the method of adding chains.Firstly,three basic models of the coupled mechanism are built by adding coupled chains,based on the 3-PRRR symmetric parallel-mechanism.Then,one of the basic models is selected and designed for two kinds of the symmetric coupling mechanisms according to the different coupling chains.Finally,a single coupled chain is taken as object of study to analyze its motion mode.The result shows that the two kinds of mechanisms meet th design requirement.A certain theoretical basis is provided for type synthesis of the symmetric coupling mechanisms by used of this method.关键词
