In order to investigate the influence of deformation of gas film in gas-dynamic hemispherical bearings on the output of three-floated gyroscopes in the platform initial navigation system subject to 3-DOF specific forces,a mathematical model is established to calculate the static error by solving Reynolds equation.Firstl,Reynolds equation is modified to describe gas flow in hemispherical bearings considering the effect of gas rarefaction. Secondl,it is solved by finite difference method to obtain the pressur...
