| Aiming at the problem that the input excitation of the traditional gravity field calibration method can only be within ± 1g,
which cannot meet the calibration requirements of the high-range accelerometer in the full range, a calibration method suitable for the
high-range accelerometer is proposed. First of all, analyzed the calibration principle and error sources and the accelerometer error
compensation model was established, secondly, designed the twelve position calibration scheme that is suitable for high range
accelerometer and calculation method for the calibration parameters is deduced, finally, through the precision centrifuge experiments,
verified the feasibility of calibration scheme, the validity of the calibration parameters was verified by data processing. The results show
that the calibration method is feasible and effective, and the compensation accuracy is higher than the traditional gravity field calibration
method, which provides a certain theoretical basis for engineering application. |
