Asymptotic Modal Analysis (AMA) has been developed to predict the response of structures which vibrate with a large number of modes. A combined experimental and analytical approach was used to test this theory for a plate carrying concentrated masses. A thin aluminum plate both with and without point masses was excited acoustically with white noise using various center frequencies and bandwidths, and the response was measured at several points on the plate. The experimental results demonstrated that the response at all points on the plate was essentially the same. It was also shown that the response of a single concentrated mass was different from that of the plate to which it is attached. In addition, it was shown that when two point masses are used, the mass response is dependent on the relative separation between the masses and the plate modal wavelength. All experimental results were found to confirm the predictions of AMA theory. © 1994 Academic Press Limited.
