【Abstract】 In order to study the rolling friction coefficient of the polyurethane roller on a sorting trolley running on steel track, theoretical analysis is carried out with a rolling friction model based on elastic hysteresis effect theory. A simplified ADAMS simulation model of sorting trolley is built to conduct dynamic simulation analysis, and experimental tests are made by traction on the field. The results show that the rolling friction coefficient values obtained by the theoretical calculations, from the ADAMS simulation analysis and through the field experimental tests are basically consistent with one another, which proves the feasibility of the three research methods and the reliability of the obtained rolling friction coefficient values.更多还原
