Physical Methods for Evaluating the Load of Friction Pairs of Braking Devices (Part I)

Abstract

Materials of the article apply to the physical methods for estimating the load of friction pairs of brake devices. Methods are expressed by principles influencing the physicochemical properties of materials of friction pairs and their internal and external parameters. Principles include causation, symmetry, reciprocity and equivalence, affinity, superposition (elementary and complex). The principles have been analyzed and it is shown as they extend to the energy fields of fric-tion pairs of brakes. Based on the action of the principles, the following pairs are distinguished: "mechano-thermal", "chemico-thermal" and "electro-magnetic". The materials of this article only pay attention to "mechano-thermal" energy field at electromechanical friction coupling of pairs of friction of brake devices.
