A dynamic reliability analysis method based on support vector machine and Monte Carlo simulation

摘要

An dynamic reliability analysis method based on support vector machine and finite element combined with Monte Carlo is presented for the parts in complex external conditions, it is difficult to built a dynamic reliability model including the models of the stress distribution and the joint probability density for the parts operating in an uncertain environment, the support vector machine has a good generalization ability and prediction ability, the integration algorithm based on support vector machine, finite element and Monte Carlo is excellently used to dynamic reliability simulation and calculation for complex and certain system. The method is applied to the reliability analysis of catenary parts in the high-speed electrified railway, the integration algorithm mathematic model of reliability analysis for the catenary suspension system is built, and the system reliability is analyzed by the model.
