摘　　要：为得到起重船作业过程中的响应状态和力学特性,联合仿真方法建立了起重船虚拟样机模型。并针对联合仿真在解算船体响应过程中收敛困难的问题,建立了起重船和环境干扰的解析模型,采用Adams和simulink与解析方法三者联合的计算方式,提高了仿真的收敛性和精度。综合考虑船体运动、吊机操纵、动力定位等因素,对起重船在波浪载荷、风载荷以及海流载荷作用下的作业过程进行了模拟分析。结果表明,船舶运动,海况等级以及吊机操作都对吊物系统运动响应有很大影响。为进一步研究海上起重施工作业的控制规律提供了理论依据,对减小吊钩摇摆幅度,安全高效的进行海上起重作业具有重大意义。In order to obtain accurate response and mechanical properties of offshore lifting operations, "Offshore Oil 201" crane ship was regarded as the research content, the virtual rigid flexible coupling prototype model of crane ship was established considering the flexible deformation of crane boom and sling using Adams and Simulink co-simulation methods. The analytical mathematical model of the ship motion and environmental interference was established to improve convergence and accuracy of co-simulation. The dynamic response of hoisting system was analyzed under wave load, sea current load and wind load considering the impact of hull movement, crane operation, dynamic positioning and other factors on lifting system. The results show that ship motion, sea condition and crane operation have great influence on the response of lifting system. This paper provides a theoretical basis for further study on the control law of offshore hoisting operation, and it’s of great significance to the reduction of swing range, safe and efficient offshore hoisting operations.
