摘　　要：露顶式弧门广泛应用于水电站表孔及泄水闸等工程部位,其液压启闭机油缸上铰点的位置对启闭机的容量和行程有很大影响.根据典型露顶式弧门液压启闭机的布置型式,建立了上铰点位置的计算模型,并采用几何解析方法得到了确定油缸上铰点合理位置的算法.在工程实践中,运用Mathcad软件编程,将本算法应用于某水电站表孔弧门液压启闭机的设计,既优化了油缸参数,节省了投资,同时又减少了设计工作量.Exposed radial gate is widely used in hydraulic engineering such as spillway outlet and the sluice outlet of hydropower station.The position of the upper trunnion of the hydraulic hoist of the radial gate plays a vital role in the determining of the capacity and stroke of the cylinder.According to the typical layout of exposed radial gate hydraulic hoist,the calculation model of the position of upper trunnion is established,and the algorithm of the position of upper trunnion is obtained by geometric analysis method.Finally,by using Mathcad software,the algorithm is applied to the design of the hydraulic hoist of the spillway outlet of a hydropower station,which optimizes the design parameter of the cylinder,saves investment and reduces the workload of designers.
