... of bilayer porous bearing is established. The effects of the working conditions on the lubrication performance and seepage behavior were analyzed. Findings Results show that the oil film pressure mainly occurs in the bearing convergence zone and contact pressure mainly occurs near the minimum film...

...Yali Zhang; Xiaogang Zhang; Zhongmin Jin Purpose This study aims to investigate the contact behavior of nominal curved surfaces with random roughness. Design/methodology/approach A deterministic model was applied to investigate the contact behavior. Numerical calculations were conducted...

... (ERSFD). Design/methodology/approach The governing equations of ERSFD as well as the boundary conditions are obtained based on Reynolds equation. A simplified Greenwood–Williamson model is implemented to investigate the contact behavior between the elastic ring and the journal. The interactions...

...Songtao Hu; Noel Brunetiere; Weifeng Huang; Xi Shi; Zhike Peng; Xiangfeng Liu; Yuming Wang Purpose Face contact has a strong impact on the service life of non-contacting gas face seals; the current research which mainly focuses on the face contact had appeared during the startup or shutdown...

...Sudipto Ray; S.K. Roy Chowdhury Purpose The paper's aim is to predict numerically the contact temperatures between two rough sliding bodies and to compare with the experimental results. Design/methodology/approach An elastic contact algorithm is used to analyze the normal contact between two...
