Abstract

The development of the low-frequency-vibration apparatus described in this report was done in response to a need to establish and verify vibration-pickup performance at infrasonic frequencies. The exciter design is an extension of the Dimoff type exciters1 and, in fact, many of its components are identical.

The motion of such an exciter must have very low distortion and minimal components of motion in all directions other than axial. In addition, the attainable amplitude must be large enough to produce a transducer signal that can be accurately measured. The attainable amplitude and accuracy of transducer calibration on this exciter is limited by transducer size, weight, geometry and vibration sensitivity. Examples of the types of accelerometers which can be calibrated on this exciter are servo or force balance, piezoelectric, piezoresistive and strain gage.
