STIFFNESS EVALUATION OF AEROSTATIC SPINDLE BASED ON NON-IDEAL CYLINDRICAL SURFACES

, 2019
The non-ideal cylindrical surface model based on profile measurement was built by using Geomagic Studio software, and it was imported into UG12.0 to create the aerostatic bearing simulation model, which can be simulated by using ANSYS WORKBENCH software.
