Reduction of gravity effect on the results of low-frequency accelerometer calibration

G. P. Ripper, C. D. Ferreira, R. S. Dias, G. B. Micheli


This paper describes a study on the possible sources of systematic errors during the calibration of accelerometers at low-frequencies. This study was carried out on a primary calibration system that uses an air-bearing vibration exciter APS Dynamics 129 and applying the sine-approximation method. Tests performed and actions taken to reduce the effect on experimental results are presented.
