Abstract

National Measurement Institutions have developed apparatuses that rely on impacting bodies to realize time-varying forces for dynamic calibration of force transducers. Within this manuscript, we present a reduced-order model to investigate the effects of structural and contact parameters on determining the frequency-dependent calibration function, which can be considered synonymous to the mechanical frequency response function,of the force transducer that is to be calibrated. The reduced order model is validated with experimental measurements and is then used to conduct parametric studies, wherein regions of single impact events and contact time are mapped out in parameter space. Although this study has been conducted with dynamic force calibrations in mind, the results presented here have broader impacts in modal analysis and system identification.
