Abstract

With the development of the economy, conveyors are increasingly moving toward long distances, large volumes, and high belt speeds, and the power of belt conveyors is closely related to the running resistance of conveyors. In the past, the indentation resistance is based on the material properties of the ideal conveyor belt. For example, Maxwell, Kelvin, or the three-parameter model are used for design calculation. The calculation results are still different from the actual ones, especially on the special conditions such as high temperature, high belt speeds. In this paper, the integral constitutive relation which is easier to test and better describe the memory performance of the material of the object after loading is established. It has guiding significance for the design of the belt conveyor.
