摘　　要：针对恶劣海况下吊装细长杆件产生的双摆现象而带来的作业效率低、风险高以及难以精确定位等问题,提出了一种新型多柔索减摇定姿系统(multi-tagline anti-swing and positioning system,MTAPS),采用多体动力学和牛顿经典力学方法建立MTAPS的动力学模型。试验数据表明,MTAPS可以有效抑制规则吊重和细长杆件吊重的摆动,在短时间内可使细长杆件吊重趋于相对稳定状态,在设定工况下MTAPS对规则吊重和细长杆件的平均减摇比分别在90%和85%以上。通过动力学仿真分析比较了船舶运动激励下多柔索减摇系统和MTAPS的减摇效果以及动力学特性。基于多柔索减摇系统研制的起重机防摆装置已完成实船应用,为实现海上细长杆件的快速转运和精确定位提供了一种新思路。To address the challenges of low hoisting efficiency,high risk,and difficulty in achieving accurate positioning caused by the double-pendulum phenomenon of slender-beam payloads under rough sea conditions,a novel multi-tagline anti-swing and positioning system(MTAPS)was proposed.The dynamic model of the MTAPS was established using multi-body dynamics and Newtonian classical mechanics.Experimental data indicate that the MTAPS can effectively suppress the swinging of both regular and slender-beam payload,bringing slender-beam payload to a relatively stable state in a short time.Under specified conditions,the average anti-swing reduction ratios for regular and slender-beam payload using this system exceed 90%and 85%,respectively.Additionally,dynamic simulations were conducted to compare the anti-swing effectiveness and dynamic characteristics of the multi-tagline anti-swing system with those of the MTAPS under ship motion excitation.The anti-swing device developed on the principle of anti-swing system has been applied in engineering,which provides a new idea for the rapid lifting and accurate positioning of slender-beam payload in an offshore environment.
