摘要

In recent vibration and acceleration pickup applications, for example in modal analysis, active control of vibration isolation, and inertial navigation, the phase shift evaluation of pickup has become important. However, the frequency-phase characteristics of the pickup has not been reported quantitatively from the production makers in the past. In this report, the phase shift evaluation results of three types (piezoelectric-type, servo-type and capacitance-type) of commercially available vibration and acceleration pickups are presented. The evaluations were performed using the sine-approximation method, which will be adopted in the updated ISO standards. The phase shift and the uncertainty of each pickup have been elucidated. Expanded uncertainties of less than ±6×10~(-3) rad in phase shift evaluation at 5 kHz have been obtained. Three piezoelectric type pickups manufactured by different makers are also evaluated and compared. We observed a phase shift difference of up to 4×10~(-2) rad in each sensor.
