Numerial Value Simulation Analysis of Dynamic Characteristics for Random chain Mechanism System

The problem of dynamic analysis based on reliability for the chain structures with random parameters are studied in this paper. Considering the randomness of structure parameters,the method to calculate natural frequency has been built,the structure dynamic characteristics is analyzed based on probability,and the digital characteristics for each order random variable of natural frequency is derived by using Monte Carlo random simulation methods. Finally,two examples are given,and some conclusions are obtained.
