  • A lot of researches have been done in order to investigate the dynamic characteristics of the aerostatic porous bearing, most of them used analytical approaches and only a few used experimental approaches. However the experimental condition used in the previous experimental approaches was not realistic, where the porous bearing has been fixed and only the mass supported by the bearing was allowed to move vertically. The dynamic stiffness obtained by those experimental setups may be different with the real case where the mass and the bearing move together in horizontal direction. In this paper, the dynamic characteristics of the horizontally moving aerostatic circular porous air bearings are investigated by the experimental approach. The experimental apparatus was designed to realize its real operating condition used in most industrial applications. The experimental results were compared with the previous experimental ones.
