An analytic solution is obtained for the plate-velocity statistics of a turbulent-flow excited, simply supported, rectangular flat plate. The radiated acoustic pressure is neglected as contributing to the plate excitation, leaving only the turbulent-boundary-layer pressure fluctuations as the exciting force. The mathematical model for the turbulent-boundary-layer pressure statistics is based on that of Corcos, which agrees well with experiment. Plate-velocity statistics are expressed in the forms of dimensionless cross-power spectral and power spectral densities. Plate-velocity-spectral and cross-spectral densities were obtained with a digital computer for selected flow and plate parameters. From these computed dimensionless spectra, effects of major parameters on the plate-velocity statistics were determined. A 'peak spectrum,' constructed by connecting major spectral peaks of the plate-velocity-spectral density, proved to be a useful engineering concept, inasmuch as knowledge of the 'peak spectrum' is equivalent to knowledge of the maximum plate velocity spectral density for a given set of input parameters. The computed dimensionless plate-velocity 'peak spectrum' compares well with 'peak spectra' constructed from available experimental data. [ABSTRACT FROM AUTHOR]
