Dynamics of Nonlinear Time-Delay Systems

Abstract

In this article the start-up of a horizontally, non-curved belt conveyor is simulated using a newly developed finite element model. The results of the simulations are used to determine an optimal velocity-controlled start-up procedure, specified in velocity profile and start-up time. The required (minimum) start-up time obtained from the simulations is compared to the start-up times which can be obtained from analytical approximations. Special attention is drawn to the transverse (vertical) vibration of a belt span supported by two idlers.
