摘要：In order to design antirotation wire rope, while considering the control of the axial strain and flexibility, the requirements that make the wire rope antirotation while making the axial strain little and flexibility excellent were presented. The relationship between axial force and twisting moment of wire rope with axial and rotational strain was given according to the linear stiffness coefficient. It was concluded that the twisting moment and axial strain under tensile load only depend on wire rope's geometry parameters which consist of helical angle and wire diameter. And the expression of bending stiffness was given. Through the analysis of an example, we find that the outer strand has a stronger effect on the tensile, torsional, and bending stiffness. And the closer the strand's helical angle is to 90°, the bigger the tensile stiffness and the bending stiffness are. The helical angles that give consideration to all the three stiffness coefficients can be found. These can be used for reference when designing antirotation wire rope.
