凤滩弧形闸门局部开启原型振动试验研究

Experimental Research on Fengtan Radial Gate Prototype Vibration with Partial Opening

采用先进的电子测量技术测定了凤滩水电厂弧形闸门原型的动力特性和局部开启时结构的振动反应．对闸门振动现象及机制进行了探讨，指出了闸门开启运行时的最不利泄流位置。

The dynamic character of prototype radial gate and vibration response of this structure with its partial opening are determined by advanced elecrometrical technique in Fengtan Hydropower Plant.This paper researches the phenomenon and mechanism of the gate vibration.It points out the most harmful discharge position when the gate is opening and provides useful reference basis for same type gate with partial opening.
