| 摘 要： | 拱形闸门属轻型壳体结构,在水流作用下易发生共振,甚至引起振动破坏。本文结合某控制闸工程实例,建立了拱形闸门的三维有限元模型,考虑流固耦合引起的附加质量对闸门自振特性的影响,利用有限元分析软件ANSYS进行模态分析,揭示了拱形闸门的自振频率和振型等自振特性。研究结果为最终设计方案的选定提供了理论依据,对同类闸门结构的设计具有参考意义。

| Abstract: | Arched gate is a lightweight shell structure.It prones to resonance and even causes vibration damage because of the effect of water flow.In this paper,the calculation of three-dimensional finite element model reveals the natural frequencies and mode shapes of the arched gate.The results would provide theoretical basis for the design of other similar arched gate. |
