【摘要】 本文从激励机理的角度,综述了目前国内外水流诱发闸门振动研究的成果.结合模型实验,阐述了平板闸门自激稳态响应的动力过程.文中指出,最终稳态响应是闸门底缘水流不稳定的分离与重附着和流体惯性共同作用的结果,并提出了产生稳态自激响应的必要条件.更多还原

【Abstract】 The study of flow-induced plate gate vibrations and its excited mechanism was reviewed in this paper. The self-excitation kinetic process of the plate gate was stated by model experment. The final steady re-sponce was determined by following factors: (1) the flow separation of the underside of gate and its rettachment, (2) the inertia of flow under the gate. The three conditions of steady responce was illustrated .更多还原
