Analysis of forced vibrations of conveyor belts

The paper presents the study of forced transverse vibrations of conveyor belts. Those are caused by rollers having an eccentricity, which originates either from production errors or transported material sticking to bearing rollers of the lower conveyor branch. The dynamic behavior of the belt was analyzed by solving a boundary problem described by differential equations expressed in partial derivatives and corresponding boundary conditions. The solution helped to determine modal parameters of the system - eigenfrequencies and eigenforms of vibrations, which, in their main modes, would be the basis of practical recommendations for selecting such parameters of conveyor systems and their operational modes which could prevent the system from getting into a resonance state. © Published under licence by IOP Publishing Ltd
