地震作用下磁悬浮车-桥垂向耦合动力学研究
|
摘要
以德国Transrap id高速磁悬浮列车为例,建立了高速磁悬浮列车与线桥动态相互作用模型,并对磁悬浮列车以不同速度通过不同桥跨情况下的车桥系统地震反应进行了数值模拟;研究了地震作用下,不同车速和不同桥跨对磁悬浮车-桥梁垂向耦合动力学系统的影响,得到了几点有意义的结果和结论。
In this paper,a dynamic interaction model of high-speed maglev vehicle-bridge is established,based on the configuration of German Transrapid high-speed maglev system.Seismic responses of the maglev vehicle-bridge system are simulated for different vehicle velocity and beam span.The effect of vertical coupling dynamic system of the maglev vehicle-bridge on earthquake response is researched for the different vehicle velocity and the beam span,and several significant results and conclusions are obtained.
