摘要
针对船用起重机在高海况下普遍存在的工作效率低、风险大、吊装定位精度低等问题,设计出一种船用起重机多柔索减摇系统.将多柔索减摇系统简化成船舶运动和风载荷激励的约束摆模型,利用MATLAB/Simulink对多柔索减摇系统的动力学特性进行仿真分析,并在船用起重机多柔索减摇系统的实验样机上进行了验证.实验结果表明,多柔索减摇系统的平均减摆比可达78％,证明了多柔索减摇系统的有效性.
Abstract
Aiming at the problems such as low working efficiency,high risk,and low positioning accuracy of marine cranes under rough sea conditions,a multi-tagline anti-swing system for marine cranes was proposed.The multi-tagline anti-swing system was simplified into a constrained pendulum model excited by ship motions and wind loads.MATLAB/Simulink was used to simulate the dynamics characteristics of the multi-tagline anti-swing systems,and the multi-tagline anti-swing system of ma-rine cranes was verified on the experimental prototype.The experimental results show that the aver-age wobble reduction ratio of the system may reach 78％,which proves the effectiveness of the multi-tagline anti-swing systems.
