Neuere Auswerteverfahren für die Stoßkalibrierung von Beschleunigungsaufnehmern werden vorgestellt, die auf der Modellierung des Aufnehmerverhaltens basieren. Die zur Identifikation dieser Modelle entwickelten Techniken einschließlich der Bestimmung resultierender Messunsicherheiten werden erläutert. Die Übertragung auf den Fall der Stoßkalibrierung von Kraftaufnehmern wird diskutiert und anhand der Auswertung von Messungen an der Kraftstoßkalibriereinrichtung der Physikalisch-Technischen Bundesanstalt illustriert.
Recent methods for the analysis of shock calibration measurements of acceleration transducers are presented. The methods are based on modelling the transducers’ dynamic behaviour. The techniques required for the identification of the model parameters are described including the determination of associated uncertainties. Applications of these procedures to shock calibration measurements of force transducers are discussed and illustrated by the analysis of measurements performed at the impact force calibration device of the Physikalisch-Technische Bundesanstalt.
