Abstract: In order to study the influence of temperature on the indentation rolling resistance of the belt conveyor, the method of rolling resistance test at different temperatures in the laboratory was carried out, and the data collected were processed and fitted with curves,and the curves of indentation rolling resistance and indentation rolling resistance coefficient of the belt conveyor at different temperatures were obtained.The test results show that under the condition of constant load and belt speed, when the ambient temperature is less than 0 ℃, the indentation rolling resistance and indentation rolling resistance coefficient increases with the rise of temperature; when the ambient temperature is within the range of 0 ℃ to 25 ℃, the indentation rolling resistance and indentation rolling resistance coefficient decreases with the increase of temperature; When the ambient temperature is greater than 25 ℃, the indentation rolling resistance and indentation rolling resistance coefficient increases with the rise of temperature. Secondly, when the temperature and load are constant, the indentation rolling resistance increases with the increase of the belt speed; when the temperature and the belt speed are constant, the indentation rolling resistance increases with the increase of load.
