Reliability Analysis of Dynamical Strength for Crank-Rocker Mechanism Based on Assur-Group Method

Abstract:

In order to analyze dynamical strength reliability of mechanism, in taking the component section sizes, the material strength, the material density and acceleration of gravity as the random variables, and basing on the movement analysis and the dynamical analysis while taking the Assur-Group as the unit, the method of dynamical strength reliability analysis for the crank-rocker mechanism was established. The example was analyzed with using Monte Carlo (MC) method. The result indicates that computing speed of this method is high, precision of this method is high, and it has good universal property. It can be used in scientific research and the engineering practice.
