Evaluation of External Load on the Winder considering the Friction of Wire

Abstract

In order to evaluate the external pressure acting on the winder by multiple-layer tension wire, in this research, a numerical analysis method was developed considering the contact of wire. By applying this method, the material properties of wire, such as the coefficient of friction of wire in the axial direction, the elastic modulus of wire in both axial direction and circumferential direction, have a great influence on the external pressure acting on the winder. However, the coefficient of friction of wire in the circumferential direction has little influence on the external pressure acting on the winder.
