摘　　要：为了研究潜器水下拖曳系统各参数对操纵运动响应的影响,采用缆索动力学数值仿真方法对拖曳系统的运动响应灵敏度进行分析。在集中质量法建立拖曳缆动力学方程的基础上,拖曳深度变化和拖曳缆张力变化作为分析指标,拖曳系统操纵运动为变速直线运动和匀速回转,计算系统各参数的敏感性指数,从拖曳操纵参数和结构参数两方面分析参数变化对潜器水下拖曳系统操纵运动的影响,通过敏感性分析确定不同参数对拖曳系统运动响应影响的重要性大小。有助于在工程应用中实现快速、正确地调节拖曳系统的运动状态,为设计潜器水下拖曳系统和简化系统的操纵运动方程提供理论支撑。In order to study the influence of various parameters of underwater submersible towed system on the maneuvering motion response,the cable dynamics numerical simulation method is used to analyze the motion response sensitivity of the towed system.Based on the dynamic equation of the towed cable established by the lumped mass method,the variation of the towed depth and the tension of the towed cable are taken as the analysis indexes.The maneuvering motion of the towed system is variable speed linear motion and uniform rotation,and the sensitivity index of each parameter of the system is calculated.The influence of parameter changes on the maneuvering motion of underwater submersible towed system is analyzed from the two aspects of towing manipulation parameters and structural parameters.The importance of the influence of different parameters on the motion response of the towed system is determined by sensitivity analysis.It is helpful to adjust the motion state of the towing system quickly and correctly in engineering application,and provides theoretical support for designing underwater submersible towed system and simplifying the maneuvering motion equation of the system.
