摘要
针对现有海上吊装模拟方法不能有效考虑浮吊船舶—系泊系统—吊物系统之间的动态耦合,难以实现基座回转、吊臂变幅连续模拟问题,基于Matlab/Simulink、ADAMS联合仿真平台建立了海上吊装作业全耦合动力分析模型,探究了中长周期波作用下波浪周期、吊缆收放、基座回转、吊臂变幅等参数变化对吊装作业系统动力响应的影响规律.结果表明,波浪周期接近吊物系统固有周期时会引发共振,导致吊物摇摆幅值显著增加.基座回转、吊臂变幅等因改变了吊物的空间位置从而引发了浮吊船舶倾覆力矩的变化,进而对浮吊船舶运动响应产生显著影响.当基座回转90°后,浮吊船舶的横倾角增加约2.74°.
Abstract
Existing simulation methods for offshore lifting operations fail to effectively consider the dynamic coupling between the floating crane vessel-mooring system-load system,making it difficult to simulate continuous problems such as pedestal rotation and boom amplitude variation.In this study,a fully coupled dynamic analysis model for offshore lifting operations was established based on the Matlab/Simulink and ADAMS joint simulation platform.The influence of changes in parameters such as wave period,cable payout,pedestal rotation,and boom amplitude on the dynamic response of the lifting operation system under medium to long wave periods was investigated.Results indicate that resonance occurs when the wave period approaches the natural period of the load system,leading to a significant increase in the amplitude of load sway.Changes in pedestal rotation and boom amplitude alter the spatial position of the load,resulting in changes in the overturning moment of the floating crane vessel,thereby significantly affecting its motion response.After a 90° pedestal rotation,the transverse tilt angle of the floating crane vessel increased by approximately 2.74°
