説明
A newly proposed method in ISO for calibration of vibration pick-up sensitivity is performed and compared with conventional methods experimentally. The proposed method is called sine-approximation method which is described in ISO/CD5347-1. The conventional methods are fringe counting method and minimum point method which are described in IS05347-1. Each method is carried out simultaneously on a same experimental setup using modified Michelson-type interferometer. Signal process procedures for sine-approximation method, such as phase unwrapping and uncertainty in approximation are proposed. A guide for uncertainty estimation in each method is presented. From the experimental results at 10 m/s2 in acceleration, sine-approximation method can be obtained up to 2000 Hz and its expanded uncertainty is estimated as 0.16-0.9 % at coverage factor 2. The main source of uncertainty is voltage measurement of the pick-up output. The new method has advantage on both the operational scope and its uncertainty. Obtained calibration results from each method are agreed within each uncertainty. The experimental results also show that electric and mechanical noise affect to the difference of each result. Those noises lead to inconsistency of calibration results on each method.
