An efficient computational method to solve combined motion of a Shinkansen train (bullet train in Japan) and the railway structure during an earthquake is given. The motion of the train is expressed in multibody dynamics. A simple mechanical model to express the interaction between wheel and rail during an earthquake is described. A rail element has been developed, where the motion in the plane of the cross-section of rail is expressed by multibody dynamics and the motion in the out-of-plane is expressed by FEM. A three-dimensional nonlinear spring element has been developed to express the elastic-plastic behavior in a concrete railway structure under cyclic loads during an earthquake effectively. The railway structure is modeled with various finite elements and also with rail elements. A modal method has been employed to solve large-scale nonlinear equations of motion of the train and railway structure during an earthquake effectively. Based on the present method a computer program for the simulation of a Shinkansen train running on the railway structure during an earthquake has been developed. Numerical examples are demonstrated.

Abstract. In order to analyze effectively the vibration response of the structure members of railway reinforced concrete viaducts, we have developed a new analysis method. It divides the whole railway system into vehicles/track model, and the track/structure model. Using these models, we examined the influence of various parameters of the vehicle, track and structure on the structure member vibration. As a result, the following has become clear. For example, for 20Hz or more, unsprung wheelset mass has a great influence on response of structure member. For 20-100Hz and 150Hz or more, rail surface roughness, for 60Hz or more, the stiffness of the rail pad, for less than 60Hz, the stiffness of the slab of structure and so on, have great influence on structure member vibration respectively.

An efficient computational method to solve the dynamic interaction between a highspeed train and the railway structure including derailment during an earthquake is given. The motion of the train is expressed in multibody dynamics. Efficient mechanical models to express contact-impact behaviors between wheel and the track structure including derailment during an earthquake are given. Rail and track elements with multibody dynamics and FEM combined are described. The motion of a railway structure is modeled with various finite elements and rail and track elements. A modal reduction is applied to solve the problem effectively. An exact time integration scheme has been developed that is free from the round-off error for very small time increments needed to solve the interaction between wheel and railway structure including derailment during an earthquake. Numerical examples are demonstrated.
