摘要: 基于 ANSYS 通用有限元软件平台,以某公铁两用斜拉桥为研究对象,借助梁格法及空间杆系有限元方法,建立了该桥的有限元模型,分析了其空间自振动特性及其在轻轨车辆作用下的车桥振动响应。结果表明: 车辆与桥梁的振动响应同国内外实测结果一致,车辆行驶竖向舒适性及安全性指标均满足规范要求。

Abstract: Taking a certain highway-railway cable-stayed bridge as the research object,the FEM model is established to analyze the natural frequency and mode shape characteristics,through the space bar FEM method and grillage method based on ANSYS. The coupling vibration responses of vehicle-bridge system under a running train are also calculated. Results indicate that the dynamic response between vehicle and bridge got by the proposed method is consistent with the measured results at home and abroad. At the same time,the vertical comfort and safety indicators when the vehicle is running meet the regulatory requirements.

Key words: highway-railway cable-stayed bridge, vehicle-bridge coupling, vibration
