In general, the dynamic sensitivity of a force transducer depends upon the mechanical system in which it is used. This dependence serves as motivation to develop a dynamic force transfer standard, which can be used to calibrate an application transducer in situ. In this work, we SI-traceably calibrate a hand-held force transducer, namely an impact hammer, by using a mass suspended from a thin line which is cut to produce a known dynamic force in the form of a step function. We show that this instrument is a promising candidate as a transfer standard, since its dynamic response has small variance between different users. This calibrated transfer standard is then used to calibrate a secondary force transducer in an example application setting. The combined standard uncertainty (k = 2) in the calibration of the transfer standard was determined to be 2.1 % or less, up to a bandwidth of 5 kHz. The combined standard uncertainty (k = 2) in the performed transfer calibration was less than 4 %, up to 3 kHz. An advantage of the transfer calibration framework presented here, is that the transfer standard can be used to transfer SI-traceable calibrations without the use of any SI-traceable voltage metrology instrumentation.

便携式动态力传递标准的可追溯校准和演示

通常，力传感器的动态灵敏度取决于使用它的机械系统。这种依赖性是开发动态力传递标准的动力，可用于原位校准应用传感器。在这项工作中，我们通过使用悬挂在细线上的质量对手持力传感器进行 SI 可追踪校准，该质量被切割以产生阶跃函数形式的已知动态力。我们表明该仪器是作为传输标准的有希望的候选者，因为它的动态响应在不同用户之间的差异很小。该校准的传递标准然后用于在示例应用设置中校准辅助力传感器。传输标准校准中的组合标准不确定度 (k = 2) 被确定为 2.1 % 或更低，高达 5 kHz 的带宽。执行的传输校准中的组合标准不确定度 (k = 2) 小于 4 %，最高可达 3 kHz。此处介绍的传输校准框架的一个优点是，传输标准可用于传输 SI 可追溯校准，而无需使用任何 SI 可追溯电压计量仪器。
