“…However, this contact condition also results in great contact pressure and plastic deformation of outside steel wires, which will accelerate the destruction of the surface and cause severe wear; therefore, the coefficient of friction increases rapidly at first. Then, the contact area becomes larger and contact pressure decreases, so the wear becomes slow and tends to be balance, but it is stable to different values under different sliding conditions, a similar tendency has been reported by Cruzado et al 2,3 In addition, because the friction surface consists of the outside steel wires and it is not a complete plane, some fluctuations appear in the curves. Furthermore, it can be seen that the effect of velocity on the coefficient of friction is more distinct at the stable stage.…”

The friction and wear behavior exists in ultra-deep coal mine between multi-layer winding hoisting ropes, and it decreases the rope's service life directly, which threatens the safety coal mine hoist. In order to obtain the tribological properties of winding hoisting rope, the effects of sliding velocity, displacement amplitude, and their combination on the tribological behavior of winding hoisting rope in ultra-deep coal mine were investigated on a self-made test rig. The results show that the effect of velocity on the coefficient of friction and temperature rise is more obvious than the stroke. Additionally, the mean value of the coefficient of friction in steady stage decreases from 0.721 to 0.524 with an increase in velocity and stroke at the same time. Furthermore, the temperature rise increases from about 3.43°C to 13.73°C with the velocity at stable stage, and the stroke has little influence on the temperature rise. Moreover, with the increase in velocity and stroke simultaneously, the damage in the wear region does not become more severe. In addition, the wear mechanisms include abrasive wear and adhesive wear, and its wear characteristics in the wear region are plastic deformation, pits, furrows, broken wires, cracking, and spalling.

“…All tests were performed at a frequency of 2 Hz and a pre-defined number of cycles of 150 × 10 3 (i.e., tests were not carried out until the final fracture). According to previous studies [4,15], real test conditions were simulated in the experimental campaign. The geometrical, mechanical and surface properties of the specimen are given in Table 2.…”

“…Zhou et al developed a fretting fatigue test bench that was driven by a motor-eccentric system [14] specifically for single aluminum wire fretting fatigue testing. The research group of the present paper, in collaboration with the Bundesanstalt für Materialforschung und -prüfung (BAM, Germany), also studied the wear behavior of thin steel wires with a fretting wear tribometer that was developed at BAM [4,15]. In both cases, the fretting testers developed were only for fretting fatigue or fretting wear studies, respectively.…”

This work presents the design of a modular ad-hoc fretting fatigue and fretting wear tribotester for thin steel wires. The working principles of the different modules are described, such as the displacement and contact modules. Preliminary studies for understanding the effect of crossing angle between wires on tangential force measurement has been carried out on 0.45 mm diameter cold-drawn eutectoid carbon steel (0.8% C). The results show that due to the developed wear scar geometry for high crossing angles there is a non-Coulomb behaviour that is not seen for low crossing angles.

“…On the one hand, fretting stroke is established between 0 and 300 μm [1]. On the other hand, previous works identified that premature rupture of the wires occurred for a contact force higher than 3 N [2,3]. Furthermore, it should be considered that the construction of a rope presents multiple wire contacts at different angles.…”

Abstract. Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an increase of the stress field and the following rupture of the wires due to fatigue. That is why the understanding and prediction of the fretting wear phenomena of thin wires is fundamental in order to improve the performance of steel wire ropes. The present research deals with the design of an ad-hoc fretting wear test machine for thin wires. The test apparatus is designed for testing thin wires with a maximum diameter of 1.0 mm, at slip amplitudes ranging from 5 to 300 μm, crossing angle between 0-90º, and contacting force ranging from 0,5 to 5 N. The working principle of displacement amplitude and contacting force as well as the crossing angle between the wires are described. Preliminary studies for understanding the fretting wear characteristics are presented, analysing 0.45 mm diameter cold-drawn eutectoid carbon steel (0.8% C) wires (tensile strength higher than 3000 MPa).
