Analysis of chain mechanical characteristics of mine scraper conveyor under material loading and chain clamping conditions

Abstract

Taking into account the safety factor of the conventional calculation of chain is in accordance with the two chain to bear external load is calculated, and the actual situation of the two chains of load is not uniform, this paper uses nonlinear dynamic finite element software ABAQUS, the simulation system of scraper chain under bias load, torsional vibration in the process of chain distribution should be produced stress and strain. A torsional vibration model of Kelvin-Voigt scraper chain and system based on the analysis of the vibration characteristics of material loading and clamping the chain scraper chain under torsion. Twist vibration from two adjacent scraper chain as a finite element analysis model of the boundary conditions, the finite element analysis of the stress and strain of the chain, we obtain two kinds of different conditions in the chain link stress strain response and the maximum stress and strain distribution, provide the basis for follow-up in the chain of life prediction, safety factor calculation.
