...Xianguang Sun Purpose The purpose of this study is to propose a fractal model of thermal contact conductance (TCC) of rough surfaces considering substrate deformation. Three deformation modes of the asperity of the rough surface are considered, including elastic deformation, elastic–plastic...

...Xianguang Sun; Wuce Xing Purpose The purpose of this study is to present a fractal model of thermal contact conductance of rough surfaces based on elliptical asperity. Design/methodology/approach The effects of contact load, fractal dimensional, fractal roughness and eccentricity on thermal...

...., 2016), but they are limited for high requirements on test environments. Relocation Modified bearing area curve Rough surfaces Surface wear Friction and wear exist between two relative moving components, consuming lots of energy and causing mechanical parts failure (Hu and Xu, 2016...

... of the pitting life of involute spur gears is introduced, which is based on an extension of the life model according to Ioannides and Harris for rough surfaces. To achieve the most realistic thermal elastohydrodynamic lubrication simulation and stress calculation possible, measured real surfaces and elastic...
