水工弧形闸门振动的智能半主动控制

Semi-active Intelligent Control for Responses of Radial Gate in Hydraulic Structure

弧形闸门是水利工程中广泛应用的一种闸门形式,设计弧形闸门要解决的关键问题之一是闸门的流激振动。基于MR智能阻尼器修正的Bingham模型,采用Matlab对水工弧形闸门的流激振动进行仿真分析。计算结果表明,采用MR智能阻尼器能有效的抑制闸门的振动反应。

Radial gate was one kind of popular gate applied in hydraulic project. One of the key problems in designing radial gate was to ,solve flow-induced vibration. A modified Bingham model was proposed to simulate the machinery property of MR smart damper. Simulate analysis was carried out to flow-induced vibration of radial gate in hydraulic structure with Matlab in this paper. Simulation analysis results showed that semi-active control with MR smart damper was beneficial to suppressing the vibration responses.
