Beschreibung
Zusammenfassung:	The stimulation of waves in bars, in particular at high amplitudes, is used for the calibration of acceleration and force sensors. The invention relates to a method and a device for calibrating acceleration and force sensors by means of a Hopkinson bar for controlled influencing of the signal form the signal amplitude and the pulse duration of the signals over a large amplitude range. A reference sensor and the sensor for calibration are arranged on the Hopkinson bar. At the end of the Hopkinson bar opposite the sensors the stimulation is carried out by means of an electromechanical actuator for converting an electrical signal into a mechanical force. The electromechanical actuator may be controlled by a control and regulation electronic circuit. A targeted influence and change in the acceleration and force pulse form can be achieved.
