Software Development For Wire Rope Type Determination And Design

Wire rope, widely used in various industrial fields, is one of the most important products in the metal products industry, but fatigue even sudden breaking is inevitable. And the mechanical properties of the wire rope are closely related to its own geometry structure. In this paper, software for wire rope type determination and design has been developed and applied based on Visual Basic language.Structural design principles of different wire rope strand, including cross-lay strand, parallel lay strand, compacted strand, triangular strand, and half-locked coil rope, full-locked coil rope are investigated. And the structural characteristics and application scope of the above structural of wire rope is discussed. Geometric parameters derivation of calculation formula of warrington strand and half-locked coil rope and full-locked coil rope is presented, and what is more, curve equations of the center wires and inner wires in single-layer rope and stranded rope are derived in general Cartesian coordinates.The software developed is more targeted by recommending corresponding structure of wire rope through its use, and used for structural design of new varieties. using the software the structural characteristics of wire rope and section graph of wire can be calculated, varieties include cross-lay strand, parallel lay strand, compacted strand, triangular strand, and half-locked coil rope, full-locked coil rope. Additionally, the caculation results are written to text file and the design procedure is exported to a word file. And all data are stored in database.Example design processed for typical wire ropes are illustrated using the software, and different occasions and different purposes for different structure of wire rope, whose parameters are calculated. And that the design results meet the conditions for strength and rigidity is verified. Analysis for different structure and application characteristics of different wire ropes is processed.Precise finite element parametric models for both single-layer ropes and stranded ropes are established. The models are based on the derivation of equations of single helix and double helix curves. These models are essential for further accurate prediction of these complex wire rope structures by conducting finite element analysis.
