“…During their service life, broken wires appear on the wire ropes. In that respect, most codes and regulations use the number of broken wires as a criterion for quantifying the degradation level [4]. Moreover, regarding the low alloy steel composition and the environmental conditions (marine atmosphere, pollution, rain, etc.…”

In this work, we investigate the behavior of wire ropes when they are subject to corrosion damage. The method is based on accelerated corrosion using experimentation as well as a theoretical predictive model. The experimental approach used static tensile tests on corroded strands. A loss in rigidity and decrease of the ultimate force was observed. For the predictive model, the residual ultimate force was evaluated at a time t in function of the initial diameter, the residual diameter at time t and the ultimate force of the original strand. Given that the obtained residual force evolution depending on the strand's fraction of life matched for both methods, the proposed predictive model can be used by engineers to assess if the wire rope needs to be changed to ensure a good maintainability of structures. Actually, when the applied force on the wire rope approaches its residual bearing force determined by a measure of the residual diameter, the wire rope removal is mandatory.

“…In the past, several studies have been conducted on the related performance of wire ropes by many scholars. To investigate the failure behaviors of the wire rope, Chaplin [10] discussed the degradation mechanisms of wire rope used in three different applications and proposed that maintenance policy, inspection methods, and frequency must recognize the degradation mechanisms and deterioration rates applicable to the operating conditions. Schrems and Maclaren [11] designed a series of experiments to determine the cause of the early retirement of an in-service hoisting rope.…”

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.

“…Torkar and Arzensˇek 2 analyzed the failure of hoisting wire ropes, discovered fatigue fracture characteristics of steel wires, and observed the fatigue crack source on the surface caused by decarbonization. Chaplin 3 discussed the effect of wear in detail on the standards for inspection and replacement of wire ropes. Atianxa [4][5][6] calculated the fatigue strength of steel wires based on their geometrical characteristics, alternating tensile stress, bending stress, and contact stress according to the actual working conditions of wire ropes.…”

Fatigue damage is the most important failure mode of wire ropes, and models of cumulative fatigue damage of wire ropes under multiple impact loads have been proposed based on the principle of microdamage linear accumulation. Fatigue damage of wire ropes under a single impact load obeys lognormal distribution, but when under different impact loads, it presents bilateral trailing phenomenon. In this work, a fitting method of wire rope fatigue life analysis under many different impact loads based on double Pareto lognormal distribution is proposed, which can accurately describe and reasonably explain the above phenomenon. The fitting result of test data calculated by double Pareto lognormal distribution is better than the result calculated by lognormal distribution and power-law distribution. This reveals that the model of double Pareto lognormal distribution can well describe the reliability degradation process of wire ropes, thereby providing guidance on the fatigue life estimation of wire ropes.
