Abstract
In this paper,acircular aerostatic bearing with periodic orifice restrictors and feed pockets is studied and the static and dynamic characteristics of the bearing are investigated through the perturbation method.The steady Reynolds equation and the perturbed Reynolds equation are solved using the finite difference method.The static load capacity and stiffness,dynamic stiffness and dynamic damping coefficients are obtained numerically.Effects of the perturbation frequency on the dynamic stiffness and dynamic damping coefficients,as well as stability of the bearing,are analyzed.Our results indicate that stability of the bearing depends on the gas-film thickness and the supply pressure.As the supply pressure increases,the gas bearing becomes less stable.With the increase of the gas-film thickness,stability of gas bearing first increases and then decreases.
