【摘 要】 为了提大跨距闸门运行的平稳性和可靠性，简化启闭机的实验过程，本文运用ADAMS软件对翻转式弧形闸门在静水环境下启闭过程进行仿真，直观地观察了翻转式弧形闸门启闭机的整个过程，对比分析了四连杆启闭机和六连杆启闭机两种方法下閘门在静水环境下闭合过程中运行特性。结果表明：其它参数相同的情况下，四连杆启闭机在闸门运行的起始阶段冲击和振动比较显著；其它参数相同的情况下，六连杆启闭机构在闸门运行结束阶段前的冲击和振动比较显著；合理的减小启闭机的驱动速度，能够减小对闸门的冲击和振动；优化启闭机的结构参数及合理的布局，同样能够减小对闸门的冲击和振动，因此，合理的选择启闭机能实现大跨距翻转式弧形闸门在闭合过程平稳运行。

[Abstract] In order to raise the running stability and reliability of the large span sluice， simplify the gate hoist process of the experiment， flip-gate hoist of the radial sluice simulation using the ADAMS software in this paper under the static water environment， visually observed the whole process of radial sluice of the flip-gate hoist， comparative analysis the sluice lifting of the four linkage flip-gate hoist and six linkage flip-gate hoist under static water environment. The simulation results showed that the sluice lifting shock and vibration in the initial of the four linkage flip-gate hoist was more significant with the other parameters were same， the sluice lifting shock and vibration before the end of operation of the six linkage flip-gate hoist was more significant with the other parameters were same， the flip-gate hoist driving velocity was decreased reasonably， the sluice lifting shock and vibration can reduce， the flip-gate hoist parameters were optimized and reasonable layout， can also reduce the impact and vibration of sluice lifting， therefore， sluice lifting can run smoothly with the reasonable choice of the large span flip-gate hoist .

水利水电工程是一项民生工程，长期以来，国外专家对水工闸门及其启闭机构进行了大量且深入的研究，积累了丰富的理论知识和经验，研制出了一批性能突出、可靠性高的闸门启闭机构。然而目前我国闸门启闭机构的技术发展比较缓慢。目前，尤其针对跨距水工闸门及启闭机构的研究文件甚少。随着国内外一些水工闸门在开启闭合过程中出现启闭超载、卡死，甚至闸门破坏等事故，闸门的运行安全越来越被重视[1-3]。

水工闸门在水利水电工程建筑物中起着泄水或蓄水的作用，通过闸门的启闭能够实调节水位、控制流量、排涝、灌溉、发电及通航等功能。……
