INVESTIGATIONS FOR THE MODEL-BASED DYNAMIC CALIBRATION OF FORCE TRANSDUCERS BY USING SHOCK FORCES

To investigate and validate the approach of a model-based dynamic calibration of force transducers by using shock excitations, numerous measurements were performed at the 20 kN primary shock force calibration device of PTB. The tests included several strain gauge force transducers of greatly differing structural design, size, weight and mechanical coupling. Previous studies proved modal oscillations of the measurement setup of various origins that limit the usable bandwidth. Their effect on the modal-based calibration method with its data analysis procedures to be developed is further investigated and discussed in this paper.
