Abstract:

The interaction characteristics of harmonic forcing excitation and panel flutter are studied analytically. Both linear and nonlinear solutions are investigated. Wide ranges of dynamic pressure and forcing frequency are covered such that subcritical responses pure forced response, supercritical responses forcing-flutter interaction, and the coexistence of both pure forced response and forcing-flutter interaction are studied. Results obtained by both harmonic balance and direct integration methods generally agree well. The technique developed here can be applied to other structural dynamics problems. Author
