  • Study on lubrication characteristics of texture surface by tiling using CFD

説明

<p>Surface texturing is used as a surface reforming technique for sliding parts. There are many reports on texture surfaces with simple dimple shapes by laser processing, etching processing and so on. In recent years, tiling processing which is one of cutting process was invented. Tiling processing has fast machining speed, high precision, and ability to create dimples having complicated shapes which could not be produced by laser- or etching-processing. On the other hand, many researches using numerical analysis about surface texturing have been reported. There are lots of reports on texture surfaces and mechanisms of hydrodynamic pressure effect is discussed with simple dimple shapes and two-dimensional analysis. Objective of our research is improvement of the load carrying capacity by specifying the optimum dimple shape and arrangement under hydrodynamic lubrication. In this research, it is reported that tribology properties under hydrodynamic lubrication with textured surface processed by tiling process by use of computational fluid dynamics. The distribution of pressure on the sliding surface is discussed comparing the shape and arrangement of the dimples. Furthermore, it is found that variation of the flow caused of surface texturing leads pressure generation and the distribution.</p>
