Abstract

This paper introduces a robust and accurate, yet simple and straightforward technique for measuring mass-normalization scale factor for each vibration mode of thin-walled structures using a piezoelectric transducer. The methodology relies on electromechanical impedance measurement and the charge frequency response function of a piezoelectric transducer attached to the structure which leads to the determination of the mass-normalized component of mode shape at the force location i.e. reference point. The scaling factor for each vibration mode is determined by comparing the arbitrary mode shape with the mass-normalized one at the reference point.
