Abstract

This paper presents a modeling technique which can be applied to any tribosystem to simulate dynamic effects in unlubricated sliding. The model is based upon straightforward methods in the study of the dynamics of mechanical systems, and incorporates an interface comprised of asperities and debris. This interface transmits displacements and forces between the two sides of the mechanical system, both of which are explicitly included in the model. The dynamic parameters obtained include displacements and velocities at any points of interest, including the two reference planes constituting the contacting surfaces of the specimen and counterface. Through the interface model, fluctuations in the friction and normal forces also can be obtained, and are of more general interest to tribologists. By means of comparisons with experimental data from strain gage measurements, and by applying the methodology to two physically different machines, the modeling approach is validated. This paper describes the modeling approach, including excitation by means of asperity and debris interactions. Also included are representative results both from numerical and experimental studies. © 1997 Elsevier Science S.A.
