AIR BEARING TESTING
Keywords:
pneumatics, air bearings, air pads, test bedAbstract
This article provides an overview of experimental air bearing testing at the Politecnico di Torino Department of Mechanics. The types and design features of the air bearings investigated at the Department are illustrated together with the test benches and instrumentation used to determine their performance. Several examples of the experimental results obtained through this work are presented.
