已经检验了通过正弦近似方法校准振动传感器。这种使用改进的迈克尔逊型激光干涉仪的方法已被提议作为 ISO 标准草案。报告了评估程序、实验设置和相位滞后不确定性的计算。已经对压电型振动传感器进行了实验评估。实验中得到了小于相位滞后评估的扩展不确定度。
The calibration of vibration pick-ups by the sine-approximation method has been examined. This method which uses a modified Michelson-type laser interferometer has been proposed as an ISO draft standard. The evaluation procedure, the experimental set-up and calculation of the uncertainty in the phase lag are reported. A piezoelectric-type vibration pick-up has been evaluated experimentally. Expanded uncertainties of less than in phase-lag evaluation have been obtained in the experiment.
