Abstract: Rotary compressors are designed more and more compact, and the compressor cylinder’s ambient pressure is designed very high to facilitate oil separation and improve efficiency. However, these designs cause the working ...

Abstract: Surface texturing is one effective means to improve bearing performance. Available studies are mainly focused on the perfectly aligned journal bearing with textures. The studies involving the effect of surface texturing ...

Abstract: In this paper, a mixed lubrication model is presented to analyze the tribological behavior of the textured journal bearings operating from mixed to hydrodynamic lubrication regimes. In particular, the effects of fluid ...

Abstract: Composite pistons are often used in heavy duty diesel engines due to its good reliability and durability. Owing to the alternating loads, fretting wear usually happens on the mating surfaces between piston crown and skirt. ...
