Kalibrering af rotationsaccelerometre

摘要

A method and system for calibrating a rotational accelerometer. The method includes attaching a rotational accelerometer to be tested to a plate fitted with and second linear accelerometers and vibrating the plate. Angular acceleration measurements from the rotational accelerometer and linear acceleration measurements from the first and second linear accelerometers are obtained during the vibrating. The linear acceleration measurements are converted into angular acceleration values, and data representing, or usable for, a comparison of the angular acceleration measurements from the rotational accelerometer and the converted angular acceleration values is generated.
