Calibration of accelerometers [PDF]

Journal of Research of the National Bureau of Standards, 1948
This paper describes three accelerometer calibrators. These calibrators were developed to provide a convenient means for calibrating lightweight accelerometers of the types used for measuring accelerations on airplanes in flight. The first calibrator is a shaking table having a sinusoidal motion with frequencies of 20 to 110 cycles per second and ...
