Abstract
A stack of piezoelectric crystals is placed on a shaft that is rotated to test a component on the shaft. An electrical signal is supplied to the stack, causing the crystals to vibrate, sending vibrations to the component as it spins. The component is enclosed in a vacuum chamber in order to provide a reduced pressure and thereby to reduce the power required to spin the component.
