“…The friction force was finally measured by the cable friction force piezoelectric sensor. Referring to the previous research, the intersection angle between the two cables affected the wear-the angle increased with the increase of the wear area [18]. The flexible cables' wear is similar to the wear between elastomers, which is very different from the rigid wear between hard cables.…”

The friction and wear of flexible cables are the main factors that cause electrical breakdown and insulation aging, and they greatly reduce the reliability and safety of robots. In order to enhance the reliability and safety of the robot, it is of great necessity to investigate the friction and wear mechanisms of the flexible cable. In this research, the friction and wear mechanisms have been discussed. The effects of relative speed, ambient temperature, and positive pressure on the flexible cables are considered by an orthogonal frictional movement. The cable friction force has been measured by a piezoelectric sensor with high natural frequency characteristics. The relations among friction and different factors affecting friction have also been discussed. The results show that the relative speed and the ambient temperature are the main factors affecting the friction and wear of the cable; the main form of flexible cable wear is mechanical-force chemical friction and wear. Those discoveries will greatly deepen the understanding of the friction and wear mechanisms of flexible cables, and will be beneficial to robot cable-reliability design.

Wire ropes are widely used in civil, mechanical and mining engineering. Safety of human life while using wire rope is always been a matter of great concern. Consequently, an efficient and safe performance of wire rope has always been an area of research. Fretting behaviour under repeated cyclic load in practical application is key player in performance of wire rope. Fretting behaviour is affected by a number of parameters viz. wire rope material, its tensile strength, lubrication and coating material and environmental factors like corrosive medium, operating temperature etc. There is a huge potential for further research in the area of fretting behaviour analysis. This paper presents a state-of-the-art review of key variables, their effect as well as remedial solution of fretting behaviour of wire rope.

“…With the development of deep resource exploitation, the multi-layer winding hoist has replaced the multi-rope friction hoist as the most suitable lifting equipment for deep coal mines in China, in particular for an ultra-deep coal mine (the hoisting height is more than 2000 m) [1,2]. Wire rope, with high axial strength and flexibility in bending, is a key part of the mine hoisting system [3,4], which determines the reliability level and the hoisting capability of the winder operations [5].…”

Friction and wear seriously affect the safety use of winding hoist wire rope and the damage is a gradual process in practical application. In this paper, the tribological properties of a wire rope under different sliding distances were investigated. The evolutions of the coefficient of friction (COF), temperature rise, and wear characteristics under different contact loads and strokes were analyzed by a series of experiments. The results show that fluctuation of the friction is large in the early stages (before 10 min) and the major peaks depend on the stroke. When the contact load is 150 N, the COF increases most rapidly. It grows from approximately 0.48 to approximately 0.61 with the sliding distance. Additionally, the temperature rise in the wear region is higher under the large stroke (30 mm) and contact load (150 N). The maximum temperature rises are approximately 7.5 • C and 7.1 • C, respectively. Furthermore, it is approximately after 7200 mm that the temperature rise reaches a relatively stable stage. The wear scar region increases with the sliding distance and the maximum wear loss is approximately 65.5 mg at a load of 150 N. The major wear mechanisms of the wire rope are fatigue and adhesion wear.
