摘要
本文根据国内外船闸廊道输水阀门运行中发现的振动情况及80年代以来我国高水头船闸设计与研究中取得的成就，讨论了船闸廊道输水阀门振动研究方面的进展。文中分析了阀门作用力的性质、量级及其影响因素，阐明了研究阀门结构动特性的重要性，介绍了结构动特性及其优化问问设计的最新技术。结合实际工程论述了应用这些新技术所取得的显著效果。这些成果可为今后高水头船闸阀门设计与科研提供参考。
According to the state for valve vibration of navigation locks in the world and the achievement for design and study in navigation locks with high-lift in China after the 80's,this paper deals with the advance of culvert value vibration for navigtion locks. The character,value and affecting factors of the dynamic load at valve are analyzed. The importance of studying the dynamic characteristic of valve structure is expounded. A new technique for the structural dynamic characteristics and their optimization are filled in the gaps in this field, the valve vibration study become even more all-sidedness. The achieved notable results are discussed using the new technique to deal with the practical projects. These results supply for reference to design and study the high-lift lock culvert valve in the future.
