Nonlinear panel response by a monte carlo approach

The vibration of clamped and simply supported elastic panels due to subsonic and supersonic turbulent boundarylayer flows is investigated by a Monte Carlo technique. The resulting generalized random forces are simulated numerically from boundary-layer turbulence spectra and the response analysis is performed in time domain. The mutual interaction between panel motion and external and/or internal airflow is included. Response studies are performed with respect to rms response, probability structure, peak distribution, threshold crossing and spectral density. The effect on the response statistics of in-plane loading, static pressure differential and cavity pressure is investigated. © 1974 American Institute of Aeronautics and Astronautics, Inc.
