本文描述了针对三种类型的压阻式加速度计（无阻尼溅射计类型、阻尼溅射计类型和无阻尼半导体类型）的低冲击和高达 10 000 ms−2 的离心机校准之间的等效程度。低冲击校准中的复数灵敏度和离心机校准中的直流灵敏度在频域的每个扩展不确定度内以及使用二阶传递函数的振动校准都具有很好的一致性。此外，还指出了离心机校准设施中的初步不确定性预算，并从机械部件和加速度计的角度进行了明确估计。
This paper describes the degree of equivalence between low-shock and centrifuge calibrations up to 10 000 ms− 2 against three types of piezoresistive accelerometer: an undamped sputter gauge type, a damped sputter gauge type and an undamped semiconductive type. The complex sensitivity in the low-shock calibration and the DC sensitivity in the centrifuge calibration are well consistent within each expanded uncertainty in the frequency domain, together with the vibration calibration using the second-order transfer function. In addition, the preliminary uncertainty budget in the centrifuge calibration facility is also indicated, and distinctly estimated from the viewpoint of the mechanical parts and accelerometers.
