摘　　要：充分考虑路桥过渡段轨面弯折变形的情况,对车辆与线路垂向耦合系统动力分析模型进行优化扩展,建立车辆与过渡段垂向耦合系统动力分析模型,并提出计算机求解的思路,可较好地模拟列车高速通过时路桥过渡段和车辆的动力特性,对实际工程具有参考意义。Through considering the bending and deformation of track surface of road and bridge transition section,this paper optimizes and expands the vertical coupling system dynamic model for train and line,establishes such model for train and road and bridge,and puts forward the idea of computer solving.It can simulate the dynamic characteristics of road and bridge transition section and train when the train is passing by,which has reference significance for engineering practice.
