Motion Reliability Analysis of the Flexible Series Mechanism in ADAMS/View

Abstract:

When there are existing flexible deformations in a mechanism, its motion reliability analysis will become more difficult. In this paper, we took a PUMA560 series mechanism as an example to analyze the flexible motion reliability. Firstly, considering the existence of its flexible characteristic we built a 3-D virtual model of this mechanism in ADAMS. Secondly, we inserted a pseudo random function that was programmed in VC++ software and used Monte Carlo method to simulate the distributions of different mechanism random errors, and then we calculated the motion reliability of this PUMA560, and this can evaluate the influence of different stochastic error on mechanism dynamic characteristics. This new method is convenient and accurate, and owns some application values for this mechanism design.
