摘　　要：分析双叶立转式开启桥的运行工况和控制要求,设计阀控比例节流调速驱动液压系统,在阐述液压系统组成与工作原理的基础上,对其调速特性进行仿真分析,通过对系统中不同控制单元的协调控制使开启桥得到理想的控制特性。Operation conditions and control requirements of twin leaves, vertically open bridge are analyzed in the article. A valve control, proportional throttle speed control hydraulic system is designed. On the basis of discussing the hydraulic system composition and work principle, its speed control characteristics are simulated and analyzed. The co-operation control on different control units, ideal control features are obtained.
