Interactive Effects of Rarefaction and Surface Roughness on Aerodynamic Lubrication of Microbearings

The aerodynamic lubrication performance of gas microbearing has a particularly critical impact on the stability of the bearing-rotor system in micromachines. Based on the Duwensee’s slip correction model and the fractal geometry theory, the interactive effects of gas rarefaction and surfac...
