Study on inner tension distribution of fiber optic cable spool with structure limitation of end plates on both sides for underwater communication in winding process
2017
In this paper, inner tension distribution of fiber optic cable spool for underwater communication in winding process is studied which adopts the structure design of end plates on both sides. We consider the axial compression force of the cable caused by the structure limitation of the end plates on both sides, analyze the force of the cable and the end plate, study on the relationship between radial compression deformation, axial extension deformation and inner tension, axial compression force of the cable in winding process, and establish the winding mechanical model of fiber optical cable spool. According to the structural parameters and the winding parameters of the spool, the distribution law of the inner tension with the winding layers is simulated, and the cable layer pressure and the end-plate deformation are also simulated. The inner strain of the spool is measured experimentally by the high-precision optical fiber strain analyzer, which is converted into the actual inner tension distribution. The accuracy of the model is verified by the comparison between the simulation results and the measured data.
