Mechanical interactions of rough surfaces. Quarterly progress report, September 30-December 31, 1985
Measurements of spinning torque as a function of spinning velocity were predicted using an elastic-plastic traction model computer program TRIBOS. Differences are noted depending upon whether the shear stress components in the plastic zone follow the elastically or viscously computed directions. It is found that at high load the viscous version affords a good fit while at low load the elastic version is superior. The behavior of lubricated concentrated contacts involving microscopically rough surfaces is explored under conditions of combined rolling, sliding and spinning with and without the presense of contaminating particles. Processing principles and techniques are being developed 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.
