Design of Porous Restriction Aerostatic Guideway for Form Measuring Instrument

Abstract:

This paper proposes a design of aerostatic guideway with the porous restriction for the vertical guideway of form measuring instrument, and analyses the design principle of the guideway.The static and dynamic characteristics of the guideway of different structures were analyzed with the software based on the finite element method, and then the optimum design was obtained by comparing the deformation and natural frequency. Finally the design of the guideway was verified by theoretical calculation and practical test that the accuracy of its various performances fully met the design requirements. The guideway can be widely applied to the form measuring instrument and other precision measuring instruments.
