A study on the wheel climb derailment on steep curves for high-speed train

ByMaorui Hou, Xing Fang, Zhongwei Feng

The nonlinear dynamic simulation model consists of eight cars based on a high-speed train, which considered coupler draft gears is the three-dimension coupling train systems is established by Multi-body dynamic software. In this paper, we set up conditions of simulation according to the actual situation. Study on the effects of calculation conditions such as the curve alignment geometry deviation, track longitudinal irregularity, wheel-rail profiles on wheel climb derailment on steep curves. Analysis on climb derailment between the different cars of a high-speed train.
