THEORETICAL STUDY ON FLEXURE RESISTANCE OF CONVEYOR BELT'

In order to reduce the flexure resistance of a beltconveyor, based on the energy theory of viscoelastic materialsunder dynamic loading, a theoretical analysis of mechanism of energyconsumption of the belt flexure is carried out when the conveyor is running.A approximate formula for the flexure resistance coefficient of theconveyor belt is derived and its validity is checked byexperiment. Based on it, the effects of various factors on the flexure resistanceare studied by means of the Matlab software with specifictechnical parameters of the conveyor. The results show that thisformula can correctly reflect the effects of various factors on the flexureresistance, and it is primarily the viscoelasticity of the belt that isresponsible for theflexure resistance. The rational viscoelastic parameters of a belt canbe obtained by using selected mating rubber, so the flexure resistance can be reduced, withsome adjustment in structural parameters of the belt and the conveyor.
