船用龙门摇摆起重机的纵向防摇校正装置的研究

The Research of the Lengthways Anti-rolling Compensative Set of Gantry Crane for Ship

介绍了船用龙门摇摆起重机的纵向防摇装置的机械、液压控制方案,采用电液比例控制方式,由角位移传感器采集的信号,控制电液比例阀的开口方向和大小,进而控制液压油缸活塞杆的伸缩,使起吊重物保持与竖直方向的夹角为0。文章对该液压系统进行了建模,选择了合适的PID控制器,来改善系统的动态响应性能,并用MATLAB的SIMULINK进行了仿真。

This paper introduces the mechanical and hydraulic controlling scheme of the lengthways antirolling compensative set of gantry crane for ship. Using electrohydraulic proportional controlling method to control the direction and size of the hydraulic proportional valve＇s opening, so as to decide the movement of piston rod of the hydraulic cylinder. In this way, the angle between the hoisting load and the elevation direction can be kept 0. This paper makes modeling on the hydraulic system, chooses appropriate PID controller to improve the dynamic response performance of the system, and simulate on it using SIMULINK .
