Debris Entrapment in Elliptical EHD Contacts


This study focuses on debris entrapment occurring in ball bearings, especially within elliptical EHD contacts. Combining both numerical simulations and experimental work, allows to investigate and quantify the effect of several contact parameters on the phenomena leading to particle entrapment. Tests for different contacting materials (steel-steel vs steel-ceramic) as well as different ellipticity ratios enable to highlight the relative importance of each of these parameters.
