摘要:: 本文简单介绍了我们十年来研究五连杆浮体闸的主要成果。首先从分析工作状态着手分析闸的运动特点,建立了五连杆浮体闸起、落及平衡的计算公式。接着讨论了模型试验,提出了动态相似的模型律。根据大量的实验资料,得出溢流水压力矩的实用图,可供设计人计算时查用。最后简单讨论了浮体闸的几个重要问题,即起动问题、自锁及自浮问题,不同步及与之有紧密联系的快降及失控问题,提出了我们对不同步产生原因及改善途径的基本观点。

Abstract:: This paper briefly introduces the main achievements of our research on five-link floating body brake in the past ten years.Firstly, the motion characteristics of the gate are analyzed from the analysis of the working state, and the calculation formulas of lift, fall and balance of the five-link floating body gate are established.Then the model test is discussed and the dynamic similarity model law is proposed.Based on a large number of experimental data, a practical diagram of the moment of overflow water pressure is obtained, which can be used by designers in calculation.Finally, several important problems of the floating body gate are briefly discussed, namely, starting problem, self-locking and self-floating problem, non-synchronization and fast descent and loss of control problem which are closely related to them.
