Free Vibrations and Random Response of an Integrally-Stiffened Panel.

Abstract

The free vibrations and random response to jet noise of an integrally-stiffened five-bay panel have been studied both theoretically and experimentally. A finite element approach was used to represent the panel for both parts of the study, and the predictions were verified by measurements on a model panel integrally machined from solid aluminum stock. The predicted modes and frequencies were used in a modal analysis of the panel's response to jet noise with a consistent finite element method being introduced to calculate the required cross-spectral modal force terms.
