摘　　要：三缆定位系统是绞吸挖泥船的重要定位设备之一,对施工作业能力和船舶安全性方面都有着重要影响。针对三缆定位系统的设计问题,从系统的主要组成、工作原理及设计流程等方面进行论述,形成不同工况下三缆系统所承受的外荷载计算流程,采用频域分析和有限元分析等方法,分析得出缆绳张力的变化规律及筒体结构的受力特点,提出缆绳选型及局部结构设计方法。结果表明,各种工况下,缆绳张力随风速增大而增大,且在同等风浪条件下,处于挖泥作业工况和避风工况的缆绳张力区别较大,应综合考虑。此外,在三缆定位的设计过程中,须对受力较大部位进行特殊考虑与重点加强。Three-cable position system is one of crucial position equipments effecting capacity and safety for cutter suction dredger.Aiming at design of three-cable positioning system,this paper introduces the main components,working principle and design process,forms the calculation process of the external loads borne by the three cable system under different working conditions,analyzes the variation law of the cable tension and the stress characteristics of the cylinder structure by using the methods of frequency domain analysis and finite element analysis,and proposes cable type selection and local structural design method.The results show that under various working conditions,the cable tension increases with the increase of wind speed,and under the same wind and wave conditions,the cable tensions under dredging operation conditions and wind shelter conditions are different quitely,which should be comprehensively considered.In addition,in the design process of three-cable positioning system,special consideration and key strengthening should be given to the parts with large stress.
