Bruns Physikalisch-Technische Bundesanstalt, Braunschweig, Germany, henrik.volkers@ptb.de ABSTRACT: sensor measuring chain signal are simultaneously This paper describes the implementation of a captured. Following the signal demodulation, the new, fast and precise linear motor drive for PTB’s primary measured acceleration peak and the sensor primary shock calibration device. This device is peak are used to determine the shock sensitivity used for monopole shock calibrations of according to accelerometers using the “hammer-anvil” principle peak 𝑆 = (1) sh according to ISO 16063-13:2001 [1] and operates in 𝑎 peak a peak acceleration range from 50 m/s² to By definition [1], the shock sensitivity S is sh 5000 m/s². calculated as the quotient of the output charge peak The main challenge of implementing this kind of value of the accelerometer and the peak value of the shock generator is accelerating a hammer to interferential measured shock acceleration velocities up to 5 m/s within distances of less than (evaluation in the time domain). It is dependent on 70 mm. the impact spectrum, the duration of impact and the In this paper,
