Abstract

Current document reports on the development and validation of advanced practical models for describing force measuring devices used for the measurement of static, continuous forces in part A as well as dynamic forces in part B of the report. In the force measurement applications, the sensitivity curve of the force measuring devices determined in the calibration gives the traceability to national standards. The measurement uncertainty in an application is mainly affected by the sensitivity stability, the influence of temperature and other parasitic components. To capture these effects an advanced model for static and continuous forces was developed in part A which describes these influences especially in respect of their contribution to the measurement uncertainty. In contrast to the static calibration procedure, the dynamic calibration of the sensor has been always challenging because of several reasons such as the sophisticated nature of dynamic measurement, insufficient structural equipment, and parasitic effects which yield higher measurement uncertainty in comparison to static measurements and therefore inappropriate characterization of the force transducers. To close this knowledge gap in the dynamic calibration, the advanced model for dynamic forces was developed in part B. To consider the dynamic properties of force measuring devices the frequency dependency of the sensitivity and the influence of parasitic influences from temperature of the force measuring devices was considered and described. The target uncertainty is 1 % for up to 100 Hz and the target uncertainty is 2 % for higher frequency range from 100 Hz up to 1000 Hz.
