Effect of Dynamic Load on Adhesive Friction at the Interface Between Friction Lining and Wire Rope of Hoist

Abstract

Abstract The acceleration, deceleration, and inertia of the friction hoist during lifting and lowering will cause the vibration of the wire rope. This vibration will cause the lifting load to become dynamic, which adversely affects the stability of the friction interface. In this paper, the relationship between the dynamic alternating load and the frictional vibration was established. The fully sliding critical value of dynamic alternating load was revealed. At the fully sliding critical value, the friction force and friction coefficient were the smallest, the adhesive friction was the smallest, and the vibration amplitude increased sharply. This is the most dangerous situation for friction systems. The fully sliding critical value is of great significance to the anti-skidding design of the hoist.
