Abstract:

Compacted strand wire ropes have higher breaking force and longer service life compared with ordinary wire ropes, and they are gradually applied in deep hoisting systems. This paper studies the stiffness characteristics of compacted strand wire ropes and ordinary wire ropes based on Costello's wire rope theory, and a dynamic model of the multi-rope friction hoisting system is established using the first kind of Lagrange equation. The numerical calculation results show that: ordinary wire ropes and compacted strand wire ropes are subjected to the same tension during the operation of the system, but the maximum amplitude of the ordinary wire ropes is about 50% larger than that of the compacted strand wire ropes. Compacted strand wire ropes have much smaller static torque and dynamic torque than ordinary ones, with a difference of 10 times between the two. Compared with ordinary wire ropes, compacted strand wire ropes have better anti-torsion mechanical properties and possess absolute advantages when applied to ultra-kilometer vertical hoisting systems.
