| Abstract: | Mathematical model of gas flow in the gas film was set up,and under a series of hypothesis,control equation of gas flow in the gap of gas film,that is the simplified Navier-Stokes equation and boundary conditions were obtained.An effective numerical simulation was applied to flow field of gas film with finite element method (FEM),which realized the preliminary determinatrion of the property parameters of air cushion probe device according to the requirment of external load. |
