英文摘要：

In order to improve the efficiency and accuracy of strand loose tube composite cable and research its strength analysis method, after the analysis on the equation of circular helix, the methods of parametric modeling and static strength analysis using ANSYS were used, which were based on the mathematical model of tensile strength. The system was combined strength design and finite element analysis which was based on knowledge engineering achieved rapid modeling and strength analysis. The way is demonstrated to be correctness and reliability with the results.
