摘要:
This paper describes a piezoelectric shaker consisting of a combination of damped resonant cylindrical elements. Material characteristics and design parameters are chosen so that the resonances of the combined elements overlap to provide “good” motion over a wide frequency range. Data from three shakers are presented to show how a suitable set of shakers can be used for the calibration of vibration pickups at frequencies up to 100 kHz.
