摘要:
因电磁波无法在水中传播,水下大容量长距离通信仅能依靠光缆等有线通信方式。对于水下航行器等需随航行体运动实时布放光缆以建立动态通信信道的应用场合,光缆线包缠绕工艺及缠绕机构的优化设计,对减小断线概率、提高水下通信的可靠性显得尤为重要。在对光缆缠绕过程及端板力学分析的基础上,提出一种以各层光缆径向变形和轴向变形为增量的逐层分析方法,建立了水下通信用光缆线包缠绕力学模型。该模型揭示了缠绕过程光缆线包内张力分布及端板变形的内在规律,以实际光缆线包结构参数和缠绕工艺参数对光缆线包内部应变、光缆层压强以及端板变形进行仿真分析,仿真结果与光缆线包缠绕过程应变实测数据符合性好。

Abstract:
Underwater high-capacity and long-distance communication relies on fiber optic cable and other wired communication methods, because electromagnetic wave can't propagate in water. Thus, optimizing the design of winding technology and winding mechanism is very important for reducing the probability of communication failure and improving the reliability of underwater communication, especially in the field of underwater vehicles, which releasing the fiber optic cable during the movement of vehicles. A layer-by-layer analysis method which adopts the radial deformation and axial deformation of each cable layer as increments is proposed, and a winding mechanical model of fiber optic cable spool is established on the basis of the mechanical analysis of the cable winding process and the end plate. The model reveals the inherent law of inner tension distribution and end-plate deformation in winding process. The simulations of inner strain and layer pressure and end-plate deformation are carried out, which adopt the parameters of spool structure and winding technology. It is shown that the simulation results of inner strain are consistent with experimental data through comparative analyses.
