Abstract
Acoustic resonance testing (ART) is a method for efficient and objective serial testing of workpieces. It nondestructively detects smallest variations in geometry, weight, and bonding and can identify holes, cracks, and other structural defects. In ART, a fully automated impact excitation is fundamental. Fully automatic, in this context, means an excitation point search and an adjustment of the excitation force controlled directly in the hammer. Moreover, it is essential to perform this excitation in a precisely reproducible process and in large series. No manual configuration steps are necessary for the user. For nondestructive ART on production lines, changes in the position of the test object must also be compensated.
To demonstrate the suitability and the advantages of the first smart impulse hammer in series testing, an ART was carried out on floor tiles on production line. For evaluation, the force sensor signal of the hammer and additionally a measuring microphone were used. Artificial intelligence and signal processing methods were used for classification. The system and results of the ART are presented in this chapter.
