水工表孔弧门振动仿真研究

Simulation Research of Radial Gate Vibration on Surface Openning of Hydraulic Structures

我国低水头弧形闸门有多起由于振动而破坏，本文利用某工程一表孔弧门结构参数进行计算机仿真研究，分析结构的固有频率和在不同激振频率性质情况下的动力响应，提出设计中应注意问题。

There are many low head radial gates failed due to vibration in our country. Computer simulation research of the radial gates on surface openning of hydraulic structures has been performed. The natural freguencies of the structure and its dynamic respones at several exciting frequencies, as well as some noticable suggestions on the radial gate design, are presented in this paper.
