4. Conclusion

The combination of the Design of Experiments (DOE) with the Finite Element Method (FEM) makes it possible to determine the effect of parameters such as material type, geometric shape, winding angle on the mechanical behavior of the cables. In addition, a Taguchi design of experiments is used to identify the optimal parameters. The effect of the optimal conditions on the failure stress was studied with an orthogonal L-network, we varied three factors on three
