“…Their stiffness is an important performance indicator for the machine tools. Static pressure spindles and slides are supported and lubricated by static pressure bearings that include aerostatic and hydrostatic bearings, which mainly use air and oil as lubricants [5][6][7][8]. The performance of static pressure bearings can be accurately calculated based on the computational fluid dynamics (CFD) method [9][10][11][12][13].…”

The stiffness of static pressure spindles and slides is affected by the phenomenon of fluid-structure interaction (FSI). Many methods have been proposed to calculate the stiffness with FSI considered. However, the influence of FSI on stiffness is still unknown. This paper studies the lateral stiffness of an aerostatic slide. The relationship between the lateral stiffness of the aerostatic slide, the lateral bearings, and the solid structure is deduced. According to the relationship, this paper proposes a theory that reveals the influence mechanism of FSI on the stiffness of static pressure spindles and slides. The proposed theory is also valid for the normal stiffness of the aerostatic slide and the thrust stiffness of an aerostatic spindle.

A simplified calculation method is evaluated to calculate the static performance of an aerostatic journal bearing with multiple orifice-type restrictors. This method adopts a one-dimension flow assumption and is a fast calculation method to design journal bearings in engineering by directly linking the structural parameters and performance parameters affecting radial bearings with nonlinear equations. In addition, this method is verified with computational fluid dynamics by two actual case studies, and it is found that the LCC difference between those two methods is less than 5% for a 200 mm diameter spindle, and less than 10% for a 100 mm diameter spindle. Subsequently, the influence of a key parameter ζi on the static performance of journal bearings is explained theoretically. This method is much easier and more intuitive compared with numerical computational methods. Furthermore, it promotes the application of aerostatic journal bearings.
