摘　　要：以某水闸一闸门为例,基于有限元分析方法,考虑了水体—闸门耦合作用,借助有限元软件以及自编子程序,分别计算并对比分析了4种不同工况下闸门的自振特性。计算结果表明:闸门自振频率较不考虑水体—闸门耦合作用时均有所降低,闸门自振基频受水体—闸门耦合作用的影响较小,对于较高阶闸门自振频率的影响比较明显;考虑水体—闸门耦合作用对闸门结构的振型有一定的影响。Taking a sluice gate as an example,based on the finite element analysis method and considering the coupling effect of water body and sluice gate,the self-vibration characteristics of the sluice gate under four different working conditions are calculated and analyzed by means of finite element software and self-compiled subroutine. The results show that the natural frequencies of the gates are lower than those without considering the water-gate coupling effect,and the fundamental frequencies of the gates are less affected by the Water-gate coupling effect and more obvious for the higher natural frequencies of the gates.
