Abstract:

The structural stability of fiber optic cabke package has a significant impact on the service status of fiber optic systems. To address the issues of long computation time and low efficiency of numerical analysis methods like finite element analysis due to strong nonlinearity and more winding layers of fiber optic cable package, an efficient computational model is established to analyze the structural stability of fiber optic cable packages. This model is used to analyze the effects of fiber optic winding patterns and uniformity of wire diameter on package structural stability. The critical values are provided for the wire diameter and uniformity that lead to the instability of fiber optic cable package. It is shown that this model improves the computational efficiency by approximately 100 times without sacrificing the computational accuracy compared to the finite element method. The "consistent residual tension" winding pattern enhances package structural stability. When the deviation of wire diameter exceeds ±3% of the standard wire diameter, the fiber displacement increases sharply, seriously impacting the package structural stability. This study holds significance for real-time analysis and control of multilayer fiber optic winding processes.
