The accuracy of the calibration methods in the previous literature_
| Description | Accuracy | Refs |
|---|---|---|
| 10 % cost of reference (DAQ NI 9775) | Vibration measurement system was working adequately | [76] |
| A closed loop calibration system | U1, U2, and S2 do not need to be measured again; the standard deviation of sensitivity is 0.0003 mV/ms−2 | [77] |
| A phase-locked resonance tracking control method based on the phase resonance principle | Acceleration stability control index of less than 0.5 % and a resonance tracking time of less than 0.1 s | [78] |
| Rapid vibration-level-adjustment for ultralow-frequency vibration exciters | Requires less vibration-level-adjustment time and improves the adjustment efficiency | [80] |
| Improved control of the linear motor | Maintaining amplitude stability over the frequency range from 0.1 to 160 Hz; the standard deviation is less than 0.01 mV/ms−2 | [84] |
| A simple but powerful method is presented | Accurate absolute calibrations with an error of 0.1 % | [88] |
| Introducing the accelerometer nonlinear scale factor | Calibration methods outperform the traditional calibration methods without high-precision orientation control | [94] |
| A low-frequency vibration generator that overcome small acceleration amplitudes and a high level of total harmonic distortion | Relative expanded uncertainty is 2.6 % at a confidence level of 95 % | [85] |
