“…The friction coefficient between the wires is set to 0.1 to consider the material property of the wires according to the description of friction coefficient in the literature. 12,15,21 Considering the actual working conditions of the braided wire rope subjected to torsional loading, the corresponding boundary conditions are imposed on the finite element model, as shown in Figure 3 (taking anticlockwise torsion for example). A torsion load is applied to the end face A using the remote displacement command to rotate the end face A about the axis of the wire rope, that is, a 645°(clockwise and anticlockwise) rotation.…”

“…With the increase in the number of revolutions per meter, the tensile strength of each meter of braided fiber rope was found to decrease by approximately 4% per revolution. Our research group [20][21][22] developed mathematical and geometric models of braided wire ropes and conducted a numerical simulation on their stress and strain characteristics for the tensile stringing of transmission lines. We then verified the effectiveness of the models by conducting a tension test.…”

Braided wire rope is vital for stringing conductors with tension in overhead transmission lines. Its structure and characteristics determine the safety and reliability of the stringing construction. Torque generated in this process can cause an uneven stress distribution, ultimately causing the wire rope to fail. This study analyzes distributions of stress and deformation in braided wire rope subjected to torsional loading. A geometric model for YS9-8 3 19 braided wire rope was established, and finite element analysis was performed on the model in different twisting directions. The simulation results show that the wires in the strands have the tendency to be screwed tightly and are in a stretched state when the lay direction of the strand coincides with its torsion direction. However, when the lay and torsion directions are opposite, the wires in the strands tend to unwind and are in a compressed state. At the same torsional angle, different torques can be generated at a particular cross-section along different twisting directions. This shows that braided wire rope has better anti-twist characteristics when twisted clockwise compared to when twisted anticlockwise. Finally, a torsion test was conducted on the braided wire rope. The results show that the change in the torque curve with respect to the torsional angle is in good agreement with the simulation results.

“…The results showed that the reductions in cross-sectional areas below 90% of the initial area cause a substantial increase in stress levels and significant decreases in the remaining life of the wire ropes. Wang et al (2017) [17] developed an FE model of wire rope and showed that stresses are unevenly distributed within the rope. They also conducted experimental tensile tests and compared the results with the simulation.…”

“…However, most actual ropes consist of several or more strands in which most wires are configured as double helices [ 3 , 15 ]. To analyze ropes with a complex topology and to include various factors in calculations, the Finite Element Method (FEM) is increasingly being employed [ 16 , 17 ].…”

This paper presents research on the bending properties of 3 × 7 19-mm wire rope commonly used in road cable barriers. A total of 19 experimental tests were conducted. In addition, two nonlinear 3D numerical models of the wire rope using beam and solid finite elements were developed. Based on these models, four numerical simulations were carried out. The numerical results were validated against the experimental ones and a very good agreement was obtained. The main result of the research is the determination of the moment–curvature relationship for the wire rope considered. The effect of prestretching on the rope performance is discussed. The numerical results are analyzed in this paper in detail, including the behavior of the wire rope under bending and analyses of the cross-sectional and contact stresses. Suggestions concerning the type of finite element for wire rope modeling are also given. The results can be used, for example, in numerical simulations of crash tests of cable barriers.

“…It was found that the local contact deformation affects the accuracy of the results. Wang et al [17] investigated the mechanical behavior of the YS9-8 × 19 braided wire rope under tensile load. By comparing the results of finite element analysis and experiment, the error between them was small, and the accuracy of the model was verified.…”

Wire rope isolators are mainly used to isolate vibration and protect precise equipment. However, the issue of regulation of vibration isolators taking into account the nonlinearity of their characteristics was poorly understood in the modern literature. In this paper, the influence of structural parameters (diameter ratio and lay pitch of the single strand, and lay pitch and bending radius of the wire rope) on stiffness-damping characteristics of the Polycal WRI was investigated by the simplified finite element analysis method. The stiffness and damping prediction models including structural parameters and material properties were established. The results showed that the stiffness-damping characteristics were the best; when the diameter ratio of wire strand was 1.1, the inside layer wire pitch length was 6 times the diameter of the wire strand, the outside layer wire pitch length was 11 times the diameter of the wire strand, the pitch length of the wire rope was 7.5 times its diameter, and the bending radius was equal to 46.5 mm. The errors of the prediction for prestiffness and softened stiffness were within 5%, and the errors of prediction for the energy dissipation coefficient were within 10%.
