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

Jixie qiangdu, 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.

Smart Active Aerostatic Bearing

, 2019
Bearings and guideways are critical components in precision positioning machines. Among diverse types of bearing technologies, passive aerostatic bearings offer excellent precision to cost ratio, yet have limited performance due to the inherent compromise between stiffness and damping, hindering the performance of the machine.

STUDY ON THE AXIAL BEARING CAPACITY OF T AEROSTATIC BEARING

Jixie qiangdu, 2016
Even a small axial vibration or an axis deflection vibration of the aerostatic bearing of DFC tool can be quite significant for ultra-precision machining. It is of great importance to obtain the accurate axial bearing characteristic（ bearing capacity and thrust stiffness） during its design,parameter optimization,machining and using process.
