    摘要:

    目前大跨度多线铁路桥梁的列车走行性受到较大的重视,其系统建模和车桥耦合振动实验研究具有重要的工程参考价值。本文以某四线大桥为背景,由实测结构模态参数结合设计相关资料,建立了桥梁基准有限元模型。然后基于此模型,由轮轨法向刚性接触关系,采用模态叠加法建立了车-桥整体系统运动方程,并结合实桥通车实验和数值计算进行了对比分析,验证了模型的正确性。最后,开展了多种工况下的车辆—桥梁耦合振动分析计算,对桥梁和车辆的动力响应以及列车运行安全性和平稳性进行了分析评价,得出了一些有工程意义的结论。

    Abstract:

    At present the train running performance on large span bridges with multiple-track line has caught great attention, and its modeling and analysis of vehicle-bridge coupling vibration has major engineering value. Taking a four line bridge as background, the baseline finite element model was set up by measured modal parameters and related design materials. Then based on this model, system motion equation of vehicle-bridge was formulated using modal superposition method according to the rigid contact relationship of the wheel and rail in the normal direction. Besides, the model was validated by comparing the results of operation bridge test and numerical simulation. At last, the vehicle-bridge coupling vibration analysis under different working conditions was carried out, and the dynamic response of the bridge and vehicle, as well as the operation safety and stability were evaluated, some useful conclusions with engineering values are drawn.
