FEASIBILITY STUDY OF VIBRATION AND SHOCK EXCITER USING ELECTRIC FIELD MODULATION OF HYDRAULIC POWER
Abstract
A feasibility study was made of the use of magnetic fields controlling shear stresses in magnetizable fluids and of electric fields controlling shear stresses in electrically active fluids, for driving a high- power, high-frequency vibration and shock exciter. This report is concerned with the actual design, construction, and testing of a prototype shock-shaker. A theoretical analysis of the electric-fluid mechanics is presented. The prototype demonstrated the technical feasibility of electric-field valving of hydraulic power in a shock-shaker. The peak accelerations and frequency bandwidth were less than the specifications because of deliberate lack of refinement of this first experimental model and because the only available fluid had a lower sensitivity than the earlier fluids.
