| 摘 要： | 目前,水力式升船机在国内外尚无投入实际运行,无实际设计、安装、运行经验可循。建立不同间隙比竖井与平衡重之间二维流固耦合数学模型,在非恒定流作用下,对不同间隙比时平衡重上升过程的水动力响应进行动态模拟。得出有利于该类升船机稳定运行的最优间隙比。

| Abstract: | Now,hydro-floating ship Lift has not run at practice in China and abroad,even we have no experiences to design,install and operate.In this paper,the fluid-structure-coupled mathematical model of different clearance ratio between the silo current and the balance weight is designed and built,which can dynamically simulates the hydrodynamic response when balance weight is lifted up and down under the action of unsteady flow.And then,the optimal clearance ratio is obtained for the stable operation of the ship lift |
