DETERMINATION OF THE TENSILE STRESS IN MINE HOISTING CABLES USING NUMERICAL METHODS
Abstract
In the paper, we addressed the simulation and numerical modeling of deformation under static loading of wire ropes used in mine hoisting installations. We presented the main types of extraction vessels (cages and skips) commonly used in the mining industry, as well as the fastening devices to the hoisting rope (DLC). A review was conducted on the primary structural models of traction cables equipping mine hoisting machines. As one of the critical assessments performed on cables in mining extraction is done at maximum static load, we constructed a virtual model of a tension testing stand for a hoisting cable using SOLIDWORKS®. Essentially, we created a virtual device in the form of an assembly consisting of multiple parts, establishing geometric connections between them. Additionally, we highlighted the cable's path over the core of the fastening device. The actual tension test was performed through a simulation under static loading of a 500 mm section of the cable. We determined the von Misses stress and overall deformations of the cable section.
