Abstract

This paper investigates the mechanical influences of the shaker armature’s mechanical structure on periodic force calibration, and hence on measurement uncertainty. A finite element model (FEM) was developed in order to perform modal and harmonic analyses of the measurement setup. The verification and validation of the FE model were continuously conducted through a measurement comparison, whereby a scanning vibrometer was used. The results show that the dynamic behaviour of the shaker armature should be taken into consideration before carrying out a periodic force measurement.
