Precision shock accelerometer calibrator
Abstract
The development of an absolute shock accelerometer calibration system is described and its precision and accuracy investigated. The system is comprised of a recoilless air gun which applies a mechanical pulse to a standard accelerometer supported and guided in an air bearing assembly. Accelerometer velocity change and output are digitally recorded and a calibration factor is calculated using an electrically interfaced computer.
