为研究高速铁路桥梁竖弯涡振对桥上列车行车安全舒适性的影响,以某大跨公铁两用斜拉桥和CRH2型动车组为背景,进行风-车-轨-桥耦合系统振动分析。基于ANSYS与SIMPACK联合仿真平台,引入桥梁涡激力数值模型,建立风-车...展开更多 为研究高速铁路桥梁竖弯涡振对桥上列车行车安全舒适性的影响,以某大跨公铁两用斜拉桥和CRH2型动车组为背景,进行风-车-轨-桥耦合系统振动分析。基于ANSYS与SIMPACK联合仿真平台,引入桥梁涡激力数值模型,建立风-车-轨-桥耦合系统振动模型,对比10 m/s平均风速下主梁发生与未发生竖弯涡振时桥梁和列车的动力响应,并分析不同列车速度的影响。结果表明:竖弯涡振会加剧桥梁和列...

Based on a long-span rail-cum-road cable-stayed bridge and CRH2 EMU,the train traveling safety and comfort on high-speed railway bridge under the action of vertical vortex-induced vibrations is studied.With an ANSYS-SIMPACK joint simulation platform,the numerical model ...MORE Based on a long-span rail-cum-road cable-stayed bridge and CRH2 EMU,the train traveling safety and comfort on high-speed railway bridge under the action of vertical vortex-induced vibrations is studied.With an ANSYS-SIMPACK joint simulation platform,the numerical model of vortex-induced forces on bridge was built up and ...
