摘要
本文提出了列车、下承式钢板梁桥空间振动的有限单元分析模型 ,采用计算机模拟方法 ,计算了提速列车以不同车速通过 3 2m下承钢板梁桥的空间振动响应 ,检算该桥是否具有足够的刚度及良好的运营平稳性 ,所得结果与实测资料相符 ,可供决策部门参考。
In the paper,one of the finite element analytical models for spatial vibration of the train and through steel plate girder bridge system is presented.The computer simulation methods are adopted and the spatial vibration responses are calculated when the train runs with speed increased over a through steel plate girder bridge of 32m span at various speeds in order to test if the bridge has sufficient rigidity with fine operation stability.The results agree well with the field test data and provide reference for policy making departments.
