Design-Induced Operational Changes of Stress-Strain State in Flat Rubber-Cable Tractive Element of Hoisting and Transporting Machine

Abstract

Main indicators of a stress-strain state (SSS) of a rubber-cable belt, the rubbercable rope for a random placement pattern and the size of the part with broken cables, including partially removed cables, with cable breakages and their random 215 amount, different conditions of belt interaction in its cross-sections of connection to structural elements of a conveyor and a lifting machine to ensure control of its tractive ability during the life cycle. Performed researches clarify the idea of the interaction mechanism of reinforcing elements in composite materials of layered structure with hard and soft layers. Obtained results can be used for development and justification of a unified technology of creation and engineering support of operation of lifting and transporting machines with flat tractive-bearing elements with increased life-span, level of efficiency and operational safety in systems of extraction, transportation and processing of minerals.
