Abstract
Many tribological systems are characterized by an interface dynamics determined by the growth and destruction of hard thin and smooth structures, so called ’patches’. These patches transmit the main part of the friction power and protect the softer pad ingredients from wear. This behavior, which is explained with the example of a brake system, can be interpreted as a kind of self-organization process. Hereby rather simple local balance equations, considering the aspects of temperature, particle flow, patch dynamics and transmitted friction power, result in a complex global tribological character. In this paper it is shown that the Cellular Automaton is a very helpful method to describe the above standing items and their correlation. In order to avoid certain numerical instabilities, the respective boundary conditions are discussed.
