摘要

深入研究影响测量结果的不确定度来源和大小，参考ISO 16063-11:1999不确定度分量表，根据实验结果和经验数据，对低频振动国家副基准测量高精度低频振动传感器套组灵敏度幅值和相移进行测量不确定度的分析和评估，为修订国家振动传递系表提供了参考依据，其灵敏度幅值和相移测量的不确定度（ =2）为16Hz参考点，0.30%和0.19；0.1Hz120Hz通频带，0.66%和0.65。

Abstract

Based on the research of uncertainty source and magnitude, the experimental results and experience, the measurement uncertainty of magnitude and phase shift of sensitivity is analyzed and evaluated according to ISO 16063-11:1999 for high precision low frequency accelaromter with amplifier at Secondary Standard for Vertical Low frequency Vibration. Therefore, it will provide a reference data to emending the nation vibration dissemination system. The relative expanded uncertainties of magnitude and phase shift of sensitivity are 0.30% and 0.19 at reference condition (16Hz), 0.66% and 0.65 over the complete frequency range from 0.1Hz to 120Hz.
