悬挂式平板闸门自振频率研究

RESEARCH ON THE VIBRATION FREQUENCY OF HANGING PLATE GATE

通过理论分析和模型试验相结合的方法,研究了苏州河挡潮闸悬挂式平板闸门的自振频率。结果表明:该闸门理论分析方法基本是正确的;其自振频率不会与水流脉动压力发生共振。

This paper studies the vibration frequency of the hanging-plate gate on the Suzhou river in Shanghai through theoretical analysis combined with modeling test. The result indicates that the theoretical analysis is correct, and no resonance will appear between the fluctuating pressure of water flow and the gate vibration frequency.
