%X In order to reduce the flexure resistance of a belt conveyor, based on the energy theory of viscoelastic materials under dynamic loading, a theoretical analysis of mechanism of energy consumption of the belt flexure is carried out when the conveyor is running. A approximate formula for the flexure resistance coefficient of the conveyor belt is derived and its validity is checked by experiment. Based on it, the effects of various factors on the flexure resistance are studied by means of the Matlab software with specific technical parameters of the conveyor. The results show that this formula can correctly reflect the effects of various factors on the flexure resistance, and it is primarily the viscoelasticity of the belt that is responsible for the flexure resistance. The rational viscoelastic parameters of a belt can be obtained by using selected mating rubber, so the flexure resistance can be reduced, with some adjustment in structural parameters of the belt and the conveyor.
