Original Abstract

The microgrooves are formed in the surface ridges by local pressure increases caused by impact loading in elliptical elastohydrodynamic contacts. It has been elucidated through isothermal Newtonian numerical analyses that the depth and the distribution of microgrooves are influenced by the height, shape and orientation of the ridges, the initial impact gap, the maximum load and time being exposed to the maximum load. The formation of the microgrooves induced by local high pressures will influence the surface failure of machine elements.
