Controlling the Load Capacity of Aerostatic Bearings via Deformable Magnetorheological-Elastomer Nozzle

Aerostatic bearing is vital to the industry of precision machines. The restrictor, which lies between air supply and bearing itself, determines the load capacity and stiffness of the bearing system. In this research, nozzles made of magnetorheological elastomer (MRE) are designed and implemented inside a commercial electromagnet. The nozzles are composed of a capillary restrictor and an air pocket (recess) at the outlet. The shape of the recess can be tweaked by changing the electric current supplied so that the outlet air pressure distribution is therefore adjusted.
