Reliable model of mechanic behavior of lifting wire ropes

Houda. Mouradi, Abdellah. El barkany, Ahmed. El biyaali


Wire ropes are used for different applications in many industrial domains, for instance, lifting system. Depending on the conditions of use, wire ropes are being degraded with direct consequences are significant changes of geometric and mechanical characteristics of its components. This results in a reduction in the resistance capacity of the wire rope with time, which could bring failure. Our work consists of studying the impact of the breaking of the wires which constitute the wire ropes on its duration, and develop models to determine the reliability of wire ropes to plan preventive maintenance actions and to change them in the appropriate time. We are equally proposing to develop a model which permits providing the resistance capacity of a wire rope in multiple levels of damage of its components and an analytical model of the relation of the reliability- damaging to illustrate the fatigue of the wires ropes’ lifting phenomenon . The approach adopted is a multi-scale approach with a total decoupling between the scale of the wire and the wire rope.
