Dynamic Characteristics and Experimental Study of Rail Belt Conveyor Operation Process

Abstract

Based on the wheel-rail belt conveyor of a new type of mining machinery conveying equipment as the research object, the mechanical properties of the operation process are studied. The differential motion equation between the trolley and the track was established by using D’Alembert’s principle, and the dynamic simulation analysis was carried out by Recurdyn to obtain the contact force between the trolley and the track during operation. The static analysis of the bracket, track and slewing part was carried out with COMSOL to explore the weak position of the overall structure. Finally, the dynamic simulation and static analysis are compared with experiments to verify the feasibility of the theory and simulation. The results show that the contact force of the trolley on the upper track is significantly greater than that of the lower track, and the trolley has a large impact force in the in-and out slewing part, which is the main component that generates noise. The position of the carrier at the seams of the rails, the connection between the track and the bracket, and the position of the inlet and exit slewing part are the places where the maximum stress occurs.
