To obtain convergent results, a cycle iteration strategy is adopted to solve the two submodels, the dynamic model and the thermal elastohydrodynamic lubrication model. The parameters …

WebFigures 13, 14, and 15 show the effect of the rolling lubricant viscosity (η 50), the viscosity pressure coefficient in the Roelands equation (z), and the limiting shear stress (τ L) on the chatter critical speed, respectively. The results indicate that excessive increasing of the first and the second parameter do not have considerable effect on the chatter critical speed; … WebThe second part gives the ‘energy equation solution’. The third part introduces methods and programs for elasto-hydrodynamic lurbication, which links the Reynolds equation with the elastic deformation equation. The final part presents application lubrication programs used in … bresha webb photos
