Modal Analysis Study On Aluminum 6061 Using Accelerometer And Piezoelectric Film Sensor
This study is conducted to determine vibration or modal parameters such as natural frequencies and mode shapes of aluminum 6061 (Al6061). If the component vibrates with frequency coherence with the natural frequency, resonance frequency will occur and structural failure might emerge. Modal anal...

| Summary: | This study is conducted to determine vibration or modal
parameters such as natural frequencies and mode shapes of
aluminum 6061 (Al6061). If the component vibrates with
frequency coherence with the natural frequency, resonance
frequency will occur and structural failure might emerge.
Modal analysis study is conducted by both simulation and
experimental methods. Simulation is conducted via ANSYS
software while impact hammer testing is done for
experimental work to determine the vibration parameter. Two
sensors are used, which are piezoelectric film and
accelerometer. Hence, the results obtained from accelerometer
showed that frequencies for mode shape 1, 2, 3, 4, 5 and 6 for
rectangular shape are 272.00Hz, 521.33Hz, 913.00Hz,
1080.67Hz, 1437.33Hz and 1803.00Hz. The results obtained
from piezoelectric film showed that frequencies for mode
shape 1, 2, 3, 4, 5 and 6 for rectangular shape are 258.33Hz,
524.67Hz, 884.33Hz, 1141.67Hz, 1399.67Hz and 1752.33Hz.
Finally, the results captured from simulation appeared that
frequencies for mode shape 1, 2, 3, 4, 5 and 6 for rectangular
shape are 291.72Hz, 647.63Hz, 841.42Hz, 1465.00Hz,
1554.00Hz and 1952.40H respectively. The results showed
that low cost sensor which is piezoelectric film proved to be
reliable in detecting the modal parameter. |
