Energy consumption of pipe belt conveyors: Indentation rolling resistance

Abstract

This paper presents a detailed approach for the calculation of the indentation rolling resistance forces of pipe belt conveyors. The viscoelastic behaviour of the belt’s rubber is modelled as a threedimensional generalized model with multiple Maxwell parameters incorporated with a Winkler foundation. The step by step calculation of the indentation rolling resistance factor is provided in this paper. Attention is also paid to the determination of the normal contact forces as concentrated load forces, exerted on each roll of an idler set. Load forces depend on the mass of the transported material, the filling ratio of the pipe, and the mass and stiffness of the belt.
