  The Influence of the Slip Flow on Steady-State Load Capacity, Stiffness and Damping Coefficients of Elastically Supported Gas Foil Bearings

  摘要：

  The slip flow effect is considered to estimate the load capacity and the dynamic coefficients of an elastically-supported gas foil bearing when the local Knudsen number for the minimum film thickness is greater than 0.01. The compressible Reynolds equation with slip flow conditions is used to evaluate the loud capacity. The linearized dynamic coefficient equations are obtained by the perturbation methods Numerical predictions compare the static, and dynamic force performances considering slip flow at room-to-high temperate with the of elastically-supported foil bearing without slip flow for a range of hearing compliances and bearing numbers. It has been shown that the slip flow effect on the load capacity and the dynamic at high temperature is significant in the region of low bearing numbers.
