Investigation into belt deviation under asymmetric loading using MBD-DEM coupled simulations
Hoisting and Conveying Equipment and TechnologiesBelt deviation is one of the most common failure modes in conveyor systems [1,2]. It can lead to material spillage, accelerated wear of belt edges and idlers, unexpected shutdowns, and increased maintenance costs. Among the multiple factors contributing to the belt deviation, eccentric material feeding at transfer points is considered a dominant cause, as it generates an unbalanced transverse driving force acting on the moving belt [3]. In practical operating environments, this deviation tendency may be further intensified or altered by asymmetric friction conditions. For example, unilateral wetting caused by rain can reduce the local belt-idler friction coefficient, resulting in an asymmetric transverse friction distribution across the belt width [4]. In addition, belt tension affects the in-plane stiffness of the belt and thereby influences its lateral deviation response [5].
