摘要
提出了基于ANSYS正则振型的汽车、自锚式悬索桥空间振动的有限单元模型,以佛山平胜大桥车桥系统振动为研究对象,运用自编程序计算了不同车辆数目、车辆间距、不同路况以及不同车速时车流通过桥梁时车桥动力响应及冲击系数,所得结果可供自锚式悬索桥设计参考。
In this paper,a finite element analysis model for space vibration of the vehicle and the selfanchored suspension bridge is presented on the basis of normal modes by ANSYS.By taking three-dimensional coupling vibration of vehicle-bridge system in the Pingsheng Bridge as the research object,the vehicle-bridge space vibration response and impact factor are calculated by using self-developed program when the vehicles run through the bridge at different number of vehicles,vehicle spacing,road condition and vehicle speed.The results provide the reference for design of self-anchored suspension bridge.
