| 摘 要： | 为了求解车桥系统振动方程中随时间变化的刚度矩阵、质量矩阵和阻尼矩阵,采用将列车-桥梁作为一个整体系统,用能量法导出了车桥系统的刚度矩阵、质量矩阵和阻尼矩阵.用此方法对某连续钢桁梁桥的振动响应进行了仿真分析,并计算了某简支钢桁梁桥的横向振动,与实测值的波形图接近,证明该方法正确可靠. |

| Abstract: | To solve the matrices of stiff,mass and damping varying with time in vehicle-bridge vibration equations,the train and bridge were coupled together as one composite system.The vibration equations of vehicle-bridge time varying system were established by means of potential energy principle.The vibration responses of a continuous truss girder bridge were analyzed by using this method.The lateral vibration calculation results of a truss girder bridge are close to the testing values.This confirms the reliability of the method. |
