Method Study on System Reliability Calculation and Control

Abstract:

An intelligent method of reliability analysis based on compound algorithm is presented in this paper, support vector machine and analysis of finite element combined with Monte Carlo numerical simulation is integrated to improve simulation computing precision. Mathematic model of reliability calculation on catenary system and compound algorithm model are built, reliability of location supporting seat and location pipe are calculated by the method, location supporting seat and location pipe are critical force-bearing parts of catenary system in the high-speed electrified railway, and fault rate is very high, their reliability analysis is important research subject in railway system, it is difficult to built reliability model of location supporting seat and location pipe because they work in a complex and uncertain environment. In this paper, analysis method of location installation based on support vector machine and finite element combined with monte carlo is used, and the outside parameter influence on location installation is analyzed by the model.
