Abstract
In order to improve stiffness of the flotation cushion, a new type of flotation cushion with variable-section pressure equalizing groove of elastic plate for aerostatic slideway was designed. Gas film pressure distribution and load carrying capacity of this flotation cushion was studied through theoretical analysis. The grid was generated by taking advantage of overlapping stitching technique. By using the coupling calculation of the gas lubrication governing equation and elastic deformation of thin plate governing equation, the load carrying capacity and stiffness of the new flotation cushion were obtained. Some experiments were made to verify the result of theoretical calculation. The experimental results show that the stiffness of new flotation cushion is much higher than conventional flotation cushion.This new flotation cushion has a wider application space.
