这是 CIPM 关键比较 CCAUV.V-K3 在“振动”（加速度量）领域的最终报告。本次比较的目的是测量一个加速度计标准集的电压灵敏度，其主要平均值为 0.1 Hz 至 40 Hz 的 27 个频率。来自五个RMO的14个计量研究所参与了比对，其中中国计量科学研究院作为试点实验室，国家计量与工程实验室和南非国家计量院作为副试点实验室。参与者之间分发了一台单端石英弯曲伺服加速度计和一个信号调节器。除一个参与实验室外，所有参与实验室都提供了校准结果，这些结果在其声明的震级结果的扩展不确定性范围内基本一致。只有两名参与者未能对五个频率计算的 KCRV 值做出贡献。对于相移，三名参与者无法参与总共 16 个频率的 KCRV 值的计算。首次低频振动关键比较揭示了 5 个 RMO 的 14 名参与者当前的校准能力。正文 要阅读本文的正文，请单击“最终报告”。请注意，此文本出现在 BIPM 密钥比较数据库 kcdb.bipm.org/ 的附录 B 中。根据 CIPM 互认安排 (CIPM MRA) 的规定，最终报告已经过同行评审并由 CCAUV 批准发布。
This is the final report for CIPM key comparison CCAUV.V-K3 in the area of 'vibration' (quantity of acceleration). The aim of this comparison was to measure the voltage sensitivity of one accelerometer standard set with primary means at 27 frequencies from 0.1 Hz to 40 Hz. Fourteen Metrology Institutes from five RMOs have participated in the comparison with National Institute of Metrology, P.R. China as pilot lab and Laboratoire National de Métrologie et d'Essais and National Metrology Institute of South Africa as co-pilot labs. One quartz-flexure servo accelerometer of single-ended type and a signal conditioner was circulated among the participants. All but one of the participating laboratories provided their calibration results, which were mostly consistent within their declared expanded uncertainties for magnitude results. Only two participants failed to contribute to the KCRV values calculated for five frequencies. For phase shift, three participants could not contribute to the calculation of the KCRV values in a total of sixteen frequencies. This first low-frequency vibration key comparison revealed the current calibration capabilities of the fourteen participants of five RMOs.
