Modeling friction and wear phenomena

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