采用多体与有限元相结合的方法，有效地解决了地震作用下新干线列车(日本高速列车)与包括脱轨后结构在内的轨道结构的动力相互作用问题。列车的运动用多体动力学表示。给出了包括脱轨后在内的轮轨相互作用的有效力学模型。给出了用多体动力学和有限元方法表示的轨道和轨道单元，有效地解决了车轮与长钢轨部件之间的接触问题。轨道结构的运动由各种有限元以及轨道和轨道单元来模拟。编制了新干线列车-轨道结构动力相互作用分析程序，分析了地震作用下列车与轨道结构的相互作用。给出了数值算例。
A combined multibody and finite element approach is given to solve the dynamic interaction of a Shinkansen train (high-speed train in Japan) and the railway structure including post-derailment during an earthquake effectively. The motion of the train is expressed in multibody dynamics. Efficient mechanical models to express interactions between wheel and track structure including post-derailment are given. Rail and track elements expressed in multibody dynamics and FEM are given to solve contact problems between wheel and long railway components effectively. The motion of a railway structure is modeled with various finite elements and rail and track elements. The computer program has been developed for the dynamic interaction analysis of a Shinkansen train and railway structure including post derailment during an earthquake. Numerical examples are demonstrated.
