摘　　要：弧形闸门上普遍存在着振动，而振动对闸门的危害性现无统一的判别方法．针对目前判别方法存在的局限性，提出了用Ｇｒｅｅｎ函数诊断弧形闸门上的振动状态。A vibration usually happens over the radial gates.But there is no any uniform discriminance determining the vibrational harm to gate.This paper suggests that the vibrational state of the radial gates is diagnosed with Green function to eliminate the limitation of present discriminances,it may determine that the vibration effect on securities of gates.

关 键 词：弧形闸门 参数共振 时间序列 动力稳定
