dc.description.abstract |
In this research, a low cost piezoelectric ultrasonic
wave generator was developed using mathematical calculation
and finite element analysis. Then a prototype was fabricated to
compare the performance. Resonance frequency, dimensions of
design and acoustic impedance of matching layer and backing
layer were determined by mathematical calculation. To
optimize the parameters of the design, finite element analysis
was used. The layer parameters were calculated using 3D model
of Finite Element Analysis. Finally, transmitting wave
frequencies in water and air were calculated from acoustic
pressure variation, which derived as a result of simulation using
2D axisymmetric model. Arduino software was used to feed
controlled electric signal to piezoelectric material. Based on
Finite Element Analysis, the prototype device was fabricated
using Lead Zirconate Titanate as the piezoelectric ceramic,
Aluminum as the matching layer and Low Carbon Steel as the
backing layer. Terminal wires were soldered and all three were
merged together using glue gun with polymer based binders.
Testing of the prototype was performed using the Oscilloscope.
The resonance was observed at 75 kHz, 182 kHz, and 231 kHz.
It was also confirmed by Impedance vs. Frequency analysis
using Inductance Capacitance Resistance meter. |
