Amplitude-frequency response of an aluminum cantilever beam determined by piezoelectric transducers

Original language description

This work is focused on creation of appropriate finite element model of aluminum cantilever beam with applied pair of piezoelectric patch transducers. Thanks to reversible behavior of piezoelectric effect each patch transducer can represent either actuator or sensor. For precise prediction of amplitude values in numerical simulations each transducer is calibrated before attaching to the beam by strain gauges. From these experiments piezoelectric properties of each piezoelectric patch are obtained. The cantilever beam is actuated by a voltage signal applied to one of the patches. The signal is a linear chirp (sine with swept frequency) with sufficient range to affect selected natural frequencies. The time response of the beam from the piezoelectric sensor and alternatively by a laser position sensor is transformed by STFT algorithm to obtain the characteristics in time-frequency domain (spectrogram). The finite element model of the cantilever beam with piezoelectric patches was created
