摘　　要：液压启闭机启闭弧形闸门在现代水利工程中得到广泛应用。如何精准控制闸门开度是曲线型堰顶工程的一个重要问题。液压启闭机的工作原理是把活塞杆的伸长缩短直线运动转换为弧形闸门启闭的圆周运动。活塞杆的直线运动、弧形闸门的圆周运动和闸门开度形成耦合关系。把三者的坐标转换为同一坐标系,建立活塞杆的运动方程,找到连接各系统的耦合目标值,再通过数值分析,解析出活塞杆的伸缩长度与闸门开度的耦合关系,就可以通过控制液压启闭机活塞杆长度,精准控制闸门开度。The operation of hydraulic hoist arched gates has been widely adopted in modern water conservancy projects.How to precisely control the gate opening is an important issue for curved weir crest projects.The working principle of a hydraulic hoist is to convert the linear movement of the piston rod into the circular motion of the arched gate.The linear movement of the piston rod,the circular motion of arched gate,and the gate opening form a coupled relationship.By converting the coordinates of the three into the same coordinate system,establishing the motion equation of the piston rod,finding the coupling target value that connects the systems,and then through numerical analysis,deriving the coupled relationship between the piston rod retraction length and the gate opening,it is possible to precisely control the gate opening by controlling the length of the hydraulic hoist piston rod.
