- Description
- This paper presents a pseudo three dimensional analysis to predict the indentation rolling resistance of belt conveyors. Conventional methods used to analyse the indentation rolling resistance problem typically assume a bottom cover of uniform thickness bonded to a rigid substrate with no consideration of the carcass properties. This work aims to analyse the influence of the carcass construction and configuration for steel cord conveyor belts and predict the influence on the indentation rolling resistance. Due to the presence of steel cords embedded in the conveyor belt, the pressure distribution at the interface between the belt and a conveyor idler roll is not uniform. To solve this problem, a static three dimensional finite element model was developed to determine the pressure distribution and reaction forces transmitted through the belt to the conveyor idler roll. The reaction loads are then used in a two dimensional viscoelastic finite element model to determine the indentation rolling resistance for the steel cord belt. This paper investigates the influence of the conveyor belt carcass and bottom cover properties on the resulting stress distribution throughout the belt and consequently on the indentation rolling resistance. The influence of the steel cord diameter and pitch, applied load, bottom cover thickness and strain rate is investigated. A finite element method is detailed for the analysis of the stress distribution throughout the belt. A range of carcass configurations is investigated and experimental verification of the calculated stress distribution undertaken using a Tekscan™ pressure measurement system.
