Abstract

Theoretical and experimental studies of optimization of design and operating parameters during operation of friction pairs of band-shoe brakes have allowed to establish the following. A comprehensive assessment of design and operating parameters of brake friction pairs at the stage of optimization design is proposed. In the unsteady process of electrothermomechanical friction, which is usually the frictional interaction of the conjugated sections of the surfaces of the friction pairs "metal - polymer" in time with changes in parameters while observing the sequence are interconnected and mutually conditioned. Experimental studies of the energy load of friction pairs under load were conducted and the uneven linear wear of friction linings along the branches of the brake band was determined. Based on the uneven linear wear of the running surfaces of the band linings, the dynamic coefficient of mutual overlap of the brake friction pairs was determined, which was 0.42.
