Abstract

An experimental and numerical study of the lubrication effectiveness of textured surfaces with dimples possessing an internal structure is presented. A fabrication method to create dimples with different profiles is described. Thrust bearing-like specimens are textured with dimples of three different internal structural shapes: rectangle (R), oblique triangle (T1) and isosceles triangle (T2). The load-carrying capacity test results show that the dimple internal structure has a profound influence on the load-carrying capacity. Specifically, cylindrical dimples with rectangular cross-sectional shape produce more load-carrying capacity than those with triangular profile. Also, presented are the results of a mass-conservative algorithm that predicts the performances of dimples with different internal structural shapes. The simulation results indicate that the higher load-carrying capacity produced by the cylindrical dimple is due to the better pressure building capacity as a result of the converging step shape.
