Simulation Analysis and Experiment Study on Instantaneous Temperature Field of Disc Brake for Mine Belt Conveyor

According to the structure and working principle of the disc brake and the operating theory of the belt conveyor,based on the theory of heat transfer and tribology,a mathematical model of the heat transfer of the brake disc was established to determine the loading method of the thermal load. The ANSYS simulation tool loaded the brake disc with a thermal load,and obtained the instantaneous temperature field distribution of the brake disc during the entire braking process. The same theory and method were used to simulate and test the brake disc instantaneous temperature field on the built test bench. Finally, the correctness and feasibility of the finite element simulation analysis method was verified by the experiment results. It provides a theoretical basis for the structural design and optimization of the belt conveyor brake for coal mine.
