“…According to equation (19), if the axial load of the end face of the wire rope was known, the relevant mechanical parameters of the rope strand and wire could be obtained. However, it would be too complex to simplify and express the process if the above derivation process was adopted to directly solve the relationship between the wire rope strain and the load in the vertical state.…”

“…Both the torsion and tension were closely related to the initial helical angle of the wire rope. is indicated that the overall mechanical properties of the wire rope could change with the twist direction and the helical angle of the wire rope [19]. Wu and Cao [20] used Frenet frame and differential geometry to establish the mathematical model of the secondary spiral of wire rope.…”

Low-cost transporting vehicles are a crucial routine for orchards in the mountainous place. As the core component of the mountainous orchard carrier, the wire rope is easily damaged due to frequent handling of agricultural materials. The mechanical model of carrier wire rope is the prerequisite for studying its damage mechanism. This paper first analyzes the load-bearing characteristics of the wire rope of the carrier and then uses the theory of differential geometry and the elasticity of the wire rope to establish the mechanical model of the wire rope side strand strain ε0 and the axial load T of the wire rope end face in the erect state and the radial contact pressure Fa of the wire rope at the bending section and the mechanical model of the axial tension F and the pulley diameter D of the wire rope end face. On the basis of the mechanical model and the wire rope geometric solid model, the finite element stress analysis of the wire rope in the vertical state was carried out to verify the accuracy of the wire rope stress model. The results show that when the wire rope was in the vertical state, the wire-wire contact stress was linear directly proportional to the load on the end face of the wire rope; the wire-wire contact stress between the strands was about 12 times that within the strand; the average error between the simulated value and calculated value was about 13.6%, proving the correctness of the established wire mechanics model. When the rope and wheel were in contact, the contact pressure of the outer wire of the side strand was only related to the axial tension of the wire rope end face and the diameter of the pulley but not to the elasticity modulus of the pulley.

“…In [2,3], the axial-torsional response of spiral strands is investigated using discrete formulation. The effect of lay angle on the axial-torsional response of multi-strand ropes has been investigated in [4]. In [5,6], the structural pattern of multistrand ropes has been optimized to maximize the axial loadbearing capacity and minimize the torque in the rope.…”

“…Because the cables are subjected to significant stress, they are made of galvanised steel wires, which make the guy wires particularly sturdy [1]. Guy wire is a vital structure used for structural support [2,3]. Until now, guy wire is still being used to support tall structures as few alternatives are available.…”

Guy wires are a powerful mechanical tool used widely in all industries. Most of the applications are employed in supporting tall structures such as antenna, communication towers, transmission lines, electric poles, and erecting flare stacks on an oil and gas platform or plant. Severe wind events such as tornadoes are the primary failurein transmitting line structure in many places worldwide. So, this research aims to investigate the effect of different types of guy wire on corrosion defects. There are many lay and strand design types in the production of guy wire. The two most common are the 7-wires and 19-wires lay. There are four samples with four conditions: the first sample is not protected with any material, the second is protected by lubrication using WD-40, the third is protected using rubber hose casing, and the last is protected by a combination of both lubrication and rubber hose casing technique. The result shows that the sample protected by a combination of lubrication and rubber hose casing has no corrosion defect.
