摘　　要：为研究钢丝绳卷扬提升式垂直升船机受力均衡性控制技术,在升船机系统动力学分析的基础上,明确钢丝绳卷扬提升式垂直升船机处于悬吊状态时,承船厢运动情况和特点;划分升船机系统获得4个子系统参数,基于各个子系统在升船机系统中的耦合关系,设计三闭环控制系统;通过转矩环控制器、速度环控制器和位置环控制器对升船机系统的转矩误差、速度误差和位置误差展开补偿控制,以此提高升船机系统的受力均衡性。经验证:可有效控制升船机系统的卷筒角、承船厢纵倾角和液压缸活塞处于稳定状态,具有良好的均衡控制效果。To study the force balance control technology for a vertical ship lift with wire rope,the motion and characteristics of the ship carrying chamber of the wire rope winch vertical ship lift in the suspended state are clarified based on the dynamic analysis of the ship lift system.The ship lift system is divided into four subsystems,and a three closed-loop control system is designed based on the coupling relationship of each subsystem in the ship lift system.The torque loop controller,speed loop controller,and position loop controller are used to compensate and control the torque error,speed error,and position error of the ship lift system,improving the force balance of the ship lift system.It is verified that the proposed method can effectively control the reel angle of the ship lift system,the trim angle of the ship carrier chamber,and the piston of the hydraulic cylinder in a stable state with good balance control effects.
