摘要：

The presence of Chladni-like patterns of enhanced response on both a taut string and a thin elastic plate under single point random excitation is demonstrated theoretically using a reverberation field method of analysis. The statistics of the wavefield for the plate are established and the field correlation is shown to be a δ-function. For the string we show that the details and width of the zones of enhanced response can be found simply in terms of the autocorrelation function of the excitation. The existence of these zones of enhanced response is demonstrated experimentally on the surface of a thin elastic plate using salt sprinkled evenly to reveal lines of excess energy. © 1979.
