Monte-Carlo simulation for error analysis of 3-TPT parallel platform

DU Yong-ying

Abstract

Through analysis on 3-TPT(5DOF) parallel machine,mathematic model of error analysis was established.Based on this,the influence of length errors of legs and position errors of joints were analyzed by Monte-Carlo simulation. The results indicated that the output error of this parallel mechanism was small enough to fulfill accuracy requirements.This research established theory basis for compensation of practical error and optimization of mechanism design parameters,and additionally,provided a method for error estimation of parallel mechanism.
