摘要:
利用有限元软件ANSYS建立了一座三跨隔震桥梁三维模型,并利用Matlab编制双向隔震铁路桥梁和列车组成的车桥系统耦合振动分析程序,研究了铅芯橡胶双向隔震铁路桥梁在列车荷载作用下的动力性能.分析结果表明:隔震桥梁在横桥向的隔震周期越大,桥梁梁体在列车荷载作用下横桥向位移越大,而扭转角和竖向位移变化不明显; 桥梁横桥向的隔震周期较大时,支座阻尼对列车作用引起的桥梁梁体横桥向水平振动的衰减作用更加明显; 随着桥梁横桥向隔震周期的增大,车体横摆、侧滚振动位移响应显著; 隔震支座阻尼对车体横摆、侧滚位移响应有一定的衰减作用; 横桥向的隔震周期和隔震阻尼比的不同对车体摇头、沉浮和点头位移响应影响较小.
Abstract:
A three-dimension FEM(finite element method)model of a three-span seismic isolated bridge is established using the ANSYS program. And a coupling analysis program is written by Matlab to analyze the interaction performance of a railway and train load bidirectional seismic isolated train-bridge system. The results show that as the isolated period of the bridge(IPB)increases, the transverse displacement of the girder increases remarkably but the torsion drift and the vertical displacement changes little. When the IPB is great, the attenuation effect of the rubber bearing’s damping on transverse displacement is obvious, and the horizontal wave of the train and the side rolling displacement become severe. The damping ratio of the seismic isolation bearing can reduce the horizontal wave and side rolling displacement. The study also proves that the IPB and the damping ratio have little effect on the wave displacement, the up-and-down displacement and the nodding displacement of the train.
