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.
