- Abstract:
- This paper describes a procedure for the dynamic calibration of force transducers using sinusoidal excitations. Thereby, the main output of such a calibration is the dynamic sensitivity: the ratio between the electrical output signal of the transducer and the acting dynamic force. The force is traced back to the mass time’s acceleration. With the aid of a scanning vibrometer, the acceleration distribution can be measured and a more realistic uncertainty for the acceleration can be given. In addition, parameter identification from the resonance behaviour can be applied.
