- Abstract:
- To investigate and validate the approach of a model-based dynamic calibration of force transducers by using shock excitations, numerous measurements were performed at PTB’s 20 kN primary shock force calibration device. 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 set-up of various origins that limit the usable bandwidth. Their effect on the modal-based calibration method with its data analysis procedures, which are to be developed, is further investigated and discussed in this paper.
