Tribological Models For Solid/Solid Contact: Missing Links

Abstract

This paper presents a brief overview of the tribological information which mechanical designers need, such as equations to predict frictional forces and wear rates. This is contrasted with the forms of result that typify wear testing in research, for example, comparative rates which are meaningful only for the apparatus used. And while the 'systems nature' of tribology is well known by researchers, there is a natural tendency to overlook at least some complexities as attempts are made to isolate particular contact phenomena. Thus, both designers and researchers seek simplicity in problems which are inherently complex. This complexity is manageable, provided one is willing to deal with complete specification of the system. This paper addresses that issue, and suggests a representation for a tribosystem which incorporates features that require attention from both mechanical modelers and materials scientists. Specifically, there is a need for characterization of the dynamic behavior of tribosystems - including both specimen and counterface 'sides' of the apparatus - together with solution of the tribological problem set. A general tribosystem representation is suggested to underscore a sequence of mechanical problems which must be addressed in parallel with fundamental materials-related problems. Only when both sets are treated can the resulting systems' behavior be modeled from first principles. Thus, the new representation serves to highlight what is missing in tribological models for solid/solid contact.
