Latest Design of Sine and Shock Exciters for Calibration Purposes

Holger Nicklich, Martin Brucke

Abstract

SPEKTRA is a leading manufacturer of Calibration Systems for vibration and acoustic sensors for use in laboratory applications.<br /> Special hardware, software and system concepts have been jointly developed for the mass production of MEMS. Since in sensor production and some metrological applications extreme requirements for sine and shock levels and frequency ranges have to be met, SPEKTRA has decided to design special exciters of their own.<br /> The paper will present new designs, measurement results and examples of applications to calibration systems. The extended capabilities of the high frequency air bearing vibration exciter SE-09 will be discussed in more detail. Applications to primary and secondary calibration systems will be demonstrated and measurement results will be given.<br /> For the high shock exciters of types HOP-S and HOP-P, theoretical considerations of how to scale up their shock amplitudes without compromising highest quality signal waveforms and excellent stability of mechanical excitation will be discussed and compared with practical measurement results.<br /> Finally an outlook on further developments of vibration and shock exciters for use in calibration and sensor production will be given.
