【摘要】 运用车站桥结构动力学及车桥耦合振动车辆动力学的研究方法,采用了车桥振动理论的荷载列方法,以重庆跨座式轻轨袁家岗车站桥为研究对象,进行了轻轨列车过桥时的车桥空间耦合振动响应分析,着重研究了列车速度变化时对车站桥的挠度、乘客在站台、站厅和楼梯上的舒适度分析.车桥计算结果表明,该车站桥能够满足良好的舒适性与安全性要求.更多还原

【Abstract】 In this paper, a study on dynamic analysis of light-rail-station viaduct under moving vehicles is presented. Moving vehicles are idealized as a number of moving loads. The overhead and multi-stories’ light-rail-station viaduct is modeled by the three-dimensional finite element model. A fully computerized approach is used to assemble the equations of the motion of the dynamic system. Then based on these models and applying the time-integration to the dynamic system, the equations of motion are efficiently solved when light rail vehicle passes and the comfort of people who stands on the platform, station hall or the stairs is evaluated.更多还原
