Abstract:Power-form nonlinear contact force models are widely adopted in relatively moving parts of macro (e.g., rolling bearings considering Hertzian contact restoring force between rolling elements and bearing raceways) or micro (e.g., the micro cantilever probe system of atomic force microscopy) scale mechanical systems, and contact resonance could cause serious problems of wear, contact fatigue, vibration, and noise, which has attracted widespread attention. In the present paper, the softening/hardening stiffness c… Show more
“…Experimental testing requires sophisticated and high-cost equipment becomes major obstacle for many researchers. The third approach uses analytical mathematical formula based on contact mechanics [ 28 ], fluid mechanics [ 29 ], and biotribology [ 30 ]. Mathematical formulation is the basic concept for many researchers conducting various studies on bearing of hip joint prostheses, but solving realistic problems is very difficult using this approach and is prone to miscalculations because it is done manually or solved numerically.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
