武汉站高速列车对管帘天花结构振动影响研究

Study on high speed train influences on tube curtain ceiling structure vibration in Wuhan station

以武汉站实际工程为背景,推导了列车所引起的振动对车站装饰管帘天花结构的影响。通过分析得到了屋盖网架结构与管帘天花结构的动力响应的极值、变形分布规律以及频谱特性,并根据计算结果提出了减振措施。

With Wuhan practical engineering as background,the vibration provoked by train influences on decorated tube curtain ceiling structure were deduced.The roof space truss structure and tube curtain ceiling structure dynamic response limit value,deformation distribution rule and spectrum characteristics were obtained by analysis,the damp measures were proposed according to calculation result.
