摘　　要：锚泊定位系统用于控制大型海洋浮标在海面上的工作位置,锚泊定位位置的精度决定了锚泊系统的基准定位精度。锚泊定位系统的布放是锚泊定位的关键环节,一旦布放定位位置偏移,将影响基准定位精度,并且对海底基站平台与设备造成威胁。为了研究锚与锚链系统下落过程中的运动规律,将锚与锚链整体视为变质量系统,建立动力学模型研究变质量系统在水中下落的运动特性,分析浮标锚链入水过程中的动力学特性与环境影响因素,为锚泊系统的设计和优化提供更为科学的依据。The mooring positioning system is employed to control the operational position of large ocean buoys on the sea surface,where the precision of mooring positioning significantly determines the benchmark accuracy of the mooring system.The deployment of the mooring positioning system constitutes a pivotal step in mooring positioning.Any deviation in the deployed position adversely affects the benchmark positioning accuracy and poses a threat to the underwater base station platform and associated equipment.To investigate the motion characteristics during the descent of the anchor and anchor chain system,the entire system is conceptualized as a variable mass system.A dynamic model is established to scrutinize the motion characteristics of the variable mass system during descent in water.The dynamic attributes and environmental factors during the buoy anchor chain immersion process are analyzed,providing a more scientifically grounded basis for the design and optimization of mooring systems.
