Abstract：[Objective]Controlling the indentation rolling resistance is an important way to reduce energy loss during the operation of high-capacity and long-distance belt conveyors.Most scholars at home and abroad use the Winkler model to derive the mechanical model of indentation rolling resistance.However,there are relatively few models derived through Hertzian contact theory.It is necessary to conduct research on this situation in order to provide a scientific method for calculating indentation rolling resistance.[Methods]An indentation rolling resistance model based on Hertzian contact theory was derived,and the accuracy of the indentation rolling resistance model was verified by combining the test bench and simulation results.[Results]The results show that the indentation rolling resistance increases with the increase of belt speed and loading pressure;under the same transportation volume,increasing the belt speed ratio and increasing the material mass can both effectively reduce the indentation resistance.
