摘要

基于方位特征集的方法分析综合出数种较为实用的混合链,并对混合链和简单支链的精度、刚度进行了对比分析。最后,给出了8种弱耦合三平移机构,并给出装配条件、主动副和耦合度。分析表明,混合链比简单支链的精度和刚度均有改进;两支路自重构并联机构力稳定性好,运行精度高,控制简便。

Abstract

Several kinds of practical mixed chains is analyzed and synthesized based on using POC set theory,the stiffness and accuracy between mixed chain and simple branched chain are analyzed.At last,8kinds of weak coupling three translation mechanisms are given,and their assembly conditions,active pairs and coupling degrees are given.The analysis shows that,compared with the simple branched chains,mixed chains are greatly improved in stiffness and accuracy,the two branched selfreconstruction mechanisms have the advantages of good stability,high precision and simple domination.
