Development of a vibroacoustic system for non-destructive test in aerospace structures 2008-36-0557

The present work describes an alternative way (to ultrasound) to check the existence of superficial flaws in sandwich panels used in the aerospace industry, based in a technique inspired in the well known "tap test". In this case, however, a non-impulsive excitation is provided by a especial transducer and the acoustic response is captured with a microphone. Correlation and Deconvolution techniques are used in order to assess the system's vibroacoustic impulse response and generate a "failure" map after post-processing the results. Results and aspects in regard to its implementation and automation are described in the paper.
