Abstract

An efficient computational method to solve the dynamic interaction of a high-speed train and railway structure, including derailment and post-derailment during an earthquake, is given. The motion of the train with nonlinear springs and dampers is modeled in multibody dynamics. Mechanical models to express contact-impact behaviours between wheel and rail before derailment, and between wheel and the track structure after derailment, are given to solve the interaction during an earthquake. A simple contact model based on multipoint contact springs on the contact surface between the wheel and the track structure after derailment, are given. The railway structure is modeled with various finite elements. The combined dynamic response of the train and railway structure during an earthquake is obtained by solving nonlinear equations of the motions of the train and the railway structure subjected to the interactions between wheel and rail before derailment, and between the wheel and the track structure after derailment. Numerical examples are demonstrated.
