Research abstract
RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SERVE AS A CONTROLLER USING POSITION ERROR, AND STORED INFORMATION TO ACTUATE THE PIEZOELECTRIC DEVICES WITH MILLISECOND OR BETTER RESPONSE TIME. THE OBJECT IS A COMPLETE FUNCTIONING BEARING SYSTEM WITH USER-FRIENDLY INTERFACE TO FACILITATE INCORPORATION IN MACHINES BY DESIGNERS NOT SKILLED IN GAS BEARING DESIGN.
