Abstract

A catenary model of China high speed railway with 4-span overlap is established in this article. Through numerical simulation, the dynamic interaction of pantograph passing through the overlap at the speed of 300 km/h is calculated and analyzed. In addition, the contact force of the train running at the same speed is measured and compared with the simulation results. The simulation results are close to the line measurement results. The dynamic interaction between pantograph and catenary is significantly enhanced at overlap span, which becomes more obvious with the increase of speed.
