船用起重机减摇控制系统设计与试验研究

随着航运业发展,追求效率的今天,船舶起重机越来越广泛的用于船与船、船与岸之间的货物装卸,成为深远海工程作业不可或缺的装备之一。由于船舶受到风、浪、流、涌等海洋环境载荷的影响,起重机的吊重会出现较大的摇晃,进而影响起重机的作业效率和安全性,严重时还将会导致严重的安全事故和环境污染,造成生命财产损失。因此,针对起重机吊重摇摆的抑制问题,设计一种船舶起重机减摇系统,减小起重机作业过程中吊重产生的摆动,对提升起重机的作业效率及安全性有重要的意义。本文针对带折叠减摇臂式船用减摇起重机装置提出了三种控制方案,并通过实验验证其综合减摇效果达到60%以上,充分验证了控制方案的正确性与可行性。

Design and experiment of anti-swing controlsystemfor marine crane

Under the influence of marine environment such as wind, wave and current, the hoisting of ship cranes will cause severe swings, which will affect the normal operations and lead to accidents. Heave movement will not only affect normal operations, but also lead to serious safety accidents and environmental pollution. In order to solve this problem, a ship crane anti-swing system is designed to reduce the swing of crane during the operation process, which is of great significance for improving the efficiency and safety of cranes. three kinds of control schemes for the anti-swing crane with folding and rocking arm type ship are proposed in this paper. Through the experiment, it is proved that the comprehensive anti roll effect is above 70%, which fully validates the correctness and feasibility of the control scheme.
