基于Fluent的径向推力联合气体静压轴承静态性能的研究

erostatic bearing are widely used in industry for its high rotational accuracy, lower rise in temperature at high speed and free of pollution. In this paper, the mathematical model of radial-thrust aerostatic bearing is derived. Further on, the pressure distribution inside the bearing is simulated with Fluent. Then, the effects of supply gas pressure, diameter of orifice on axial static characteristics of gas bearing have been researched. Finally the static stiffness of the bearing is measured experimentally, the result of the experiment coincide with the simulation result.
