Analysis and design of compacted IWRC meshed model under axial strain

Abstract

Wire ropes are one of the most complex shapes due to the helical coiling of wires. It is difficult to generate a meshed model of even the classical circular wire rope. In this paper a more complex form which is known as compacted wire rope is modeled in 3D. The originality of this work is that, it is the first time a multi-layered compacted wire rope is generated and brought to the literature. The written code permits to create any length of compacted independent wire rope core geometry and to change wire radiuses and pitch lengths easily. Meanwhile flexibility of the code makes it easier to generate different kind of compacted independent wire rope core which is ready for numerical analysis. Compacted wire ropes have increased wear resistance and tensile strength. Due to its flattened surface their usage on a sheave or a pulley provides less wearing and breaking of wires while more tensile strength and increased lifetime. With the compaction process diameter of the wire rope decreases which results a decrease on the reaction moment also. This modeling issue can be used to create new type of complex wire rope models in the future.
