In this paper, an experimental identification method of impact force acting on aluminum plates using Lamb wave is proposed. The present method enables real-time identification of impact force location using Lamb wave. First, a transfer matrix to relate an impact force to PZT sensor responses is determined experimentally by using an impulse hammer test. Next, the location is identified using arrival time differences of Lamb wave, and the history of the applied force is identified using measured strain responses. For precise force location identification, the location of impact force is improved based on optimization approach. The validity of the present identification method is verified through the experimental results of aluminum plates.
