A Method Used for Mechanism’s Motion Accuracy Reliability Analysis

Abstract:

Dynamic responses of a certain system could vary with the place, environment and time of use even if the system itself did not change. Traditionally, kinematical reliability analysis of a multi-body mechanism was a hard point in the reliability field. In order to obtain a large sample data of mechanism’s transient kinetic characteristics, it needed to take lots of time, labor and finance input to acquire. It reported an effective method used for mechanism kinetic reliability analysis, with the combination of VC++ and CAE software’s second develop program, it built a parametric virtual test model for complex mechanism system. Where, it used multiplicative congruent method to program a pseudo-random number function that conformed to normal distribution to simulate the stochastic error distribution of the mechanism, which was convenient for the Monte Carlo parametric modeling to obtain large sample data and calculate the system kinetic reliability.
