Abstract

The derailed train may impact station buildings, which will cause serious consequences. But the corresponding research is still very limited. In the paper, the finite element models of the train, the railway and the ground is built up with nonlinear finite element software. By introducing an artificial obstacle, the train derailment and the attitude of the train after the derailment are simulated. The influence of various friction coefficients of the ground is discussed. The simulation results show that the friction coefficients of the ground will influence the speed and running time after the derailment. Significant pulling and collision between different cars of the train can be observed. The rear cars will push the front cars, which make the train moves in a “snake like” attitude. The train may collide with objects within 6.68m beside the railway.
