Reliability simulation and analysis of messenger wire bearing on electrified railways

The fault in the high-speed electrified railway mainly results from catenary system, and the fault of catenary system mainly caused by its low reliability. Messenger wire bearing is critical force-bearing parts of catenary system, its reliability has an important influence on total catenary system, so its reliability simulation and analysis is very important, it is difficult to built messenger wire bearing reliability model because it works in a complex and uncertain environment, in this paper, messenger wire bearing analysis method based on support vector machine and finite element combined with Monte Carlo is presented, integration algorithm mathematic model of messenger wire bearing analysis is built, and the outside parameter influence on messenger wire bearing is analyzed by the model.
