Paper Abstract

In this work, numerical modeling of tapping sound was introduced and verified by comparison with experimental results. Closeness of numerical results and experimental results were shown by feature indices. According to the comparison of numerical results and experimental results, sound print (tapping sound data of healthy structure) can be successfully obtained through present numerical modeling tapping sound. Also, an automatic tapping device (called a mouse robot) was developed for the efficient application of tapping sound analysis to realistic structures. To show the performance of automatic tapping device, a realistic composite structure was manufactured and tested. Test results showed the usefulness of automatic tapping device and performance of tapping sound analysis.
