Response of space shuttle surface insulation panels to acoustic pressure

The free vibration characteristics and dynamic response of reusable space shuttle surface insulation panels to acoustic random pressure fields are studied. The basic analytical approach in formulating the governing equations of motion uses a Rayleigh-Ritz technique. The pressure field is modeled as a stationary Gaussian random process for which the cross-spectral density function is known empirically from experimental measurements. The response calculations are performed in both frequency and time domains. In the time domain analysis, the random noise pressures are simulated on a digital computer and the equations of motion are solved numerically in a Monte Carlo sense. © American Institute of Aeronautics and Astronautics, Inc., 1977, All rights reserved.
