Mechanical interactions of rough surfaces. Quarterly progress report, April 1, 1985-June 30, 1985
The project, Mechanical Interactions of Rough Surfaces addresses a number of unresolved issues which impact the design of mechanical systems in which surface microtopography per se or events which occur on the microgeometric scale play a critical role. The project is an experimental/analytical investigation to: (1) Explore the behavior of lubricated concentrated contacts involving microscopically rough surfaces under conditions of combined rolling, sliding and spinning with and without the presence of contaminating particles. (2) Develop processing principles and techniques for the analysis of digitized rough surface profiles to yield surface descriptors that are predictive of functional performance and which have acceptable systematic and random error. The work is being conducted within two distinct tasks: In Task I, a rig designed and built by SKF is used to provide optical interferograms of the lubricated contact of rough surfaces along with measurements of the traction transmitted under conditions of combined rolling, sliding and spinning. The objective of Task II is to develop guidelines and techniques for the processing of surface roughness data generated in analog form by a stylus profile instrument to provide interpretable predictions of surface performance in contact.
