Obtaining the resonant frequency of piezoelectric using the Abaqus

Project Overview

In this Abaqus project, the resonant frequency of a piezoelectric material is obtained using Abaqus simulation.

The piezoelectric material used in this model is PZT-5H. The piezoelectric component has a length of 8 cm, a width of 4 cm, and a height of 1 cm.

Resonant Frequency

The resonant frequency is determined by analyzing the displacement response of the piezoelectric at different excitation frequencies.

At the resonant frequency, the amplitude of the system reaches its maximum value. Therefore, by evaluating the displacement response at different frequencies, the frequency corresponding to the maximum displacement can be identified as the resonant frequency.

Frequency–Displacement Response

To determine the resonant frequency, the displacement of the piezoelectric is obtained at different frequencies. The results are then plotted as a frequency–displacement diagram.

The peak of the displacement curve indicates the frequency at which the piezoelectric experiences its maximum amplitude. This frequency represents the resonant frequency of the system.

Obtained Resonant Frequency

According to the Abaqus simulation results, the resonant frequency of the PZT-5H piezoelectric is approximately 8475 Hz.

At this frequency, the maximum displacement or amplitude is observed in the piezoelectric component.
