Abstract
The aerostatic spindle is made up of the structure components and the fluid film. The interaction between them has important influence on the comprehensive performance of the spindle. This paper presents a new design method of aerostatic spindle based on the fluid-structure interaction method. The changes of bearing clearance caused by the structure deformation under high-pressure fluid film are considered, and the static performances of the bearing are obtained. In order to improve the performance of the spindle, the structural parameters of the bearing are optimized. The proposed design method is implemented through a self-developed aerostatic spindle.
