Abstract
"This paper introduces a device dedicated to acoustic excitation for modal analysis of plates. A particular setup is requested since the system should produce acoustic excitation with high power in the 10…120 Hz frequency range. The system comprises a signal generator, an amplifier powered by a car starter or a battery, and a subwoofer. This system permits setting the generated frequency around the resonance frequency with reasonable frequency and amplitude stability. We present the system’s design and test its performance on a rectangular plate. In our laboratory experiments, we achieved the desired structural behavior. Keywords: modal analysis, acoustic excitation, subwoofer, frequency estimation."
