摘　　要：光纤线团是潜水器航行过程实施布放,建立两节点间动态有线通信信道的关键部件,其应力分布状态直接决定水下布放性能。引入光纤微缆径向弹性参数,解释绕制过程光纤微缆的径向变形和径向与轴向变形的关系;建立光纤线团应力分布模型,对光纤线团应力分布随光纤微缆弹性参数、绕制张力的变化规律进行仿真研究,分析各参数对光纤线团贮存寿命的影响,提出光纤微缆和绕制张力设计的优化方向;对比分析线团绕制实测数据,应力分布及浴盆特征参数变化与仿真结论一致。结果表明:光纤微缆轴向弹性模量越小、径向弹性模量和弹性系数越大,有利于光纤线团的结构稳定,但会降低光纤的贮存寿命;而绕制张力越大会降低光纤的寿命,但并不影响光纤线团的结构稳定性。Fiber-optic coil is the key component to set up a dynamic wired communication channel between two nodes,which can is deployed during the movement of unmanned submersible vehicle.The stress distribution state of the coil in winding process directly determines its wire releasing performance.The radial deformation of the fiber-optic micro-cable and the relationship between its radial and axial deformations are explained by introducing its radial elastic parameters.A stress distribution model of the coil is established on the basis of the force analysis of the cable and the end plate.The variation of the stress distribution of coil with the elastic parameters of cable and winding tension is studied through simulation.Then the effect of each parameter on the storage life of coil is analyzed,and the optimization design of cable and winding tension is further proposed.Compared with the measured data of the coils,the changes of stress distribution and bathtub feature parameter are consistent with the simulation conclusions.The results show that the smaller the axial elastic modulus of cable is,the greater the radial elastic modulus and the radial elastic coefficient of cable are,the more stable the structure of coil is,but the storage life of optical fiber will be reduced;and the greater winding tension reduces the storage life of optical fiber,but does not affect the structural stability of the coil.
