On Vibration and Flutter Analysis With Free-Free Boundary Conditions

Abstract

79 A COLLOCATION FORMULATION of the vibration and flutter problems is presented in reference 1, which also gives the specific forms of the collocation equation in the cases of free-free symmetric and free-free antisymmetric boundary conditions. The purpose of the present note is to generalize the previous analysis for any combination of rigid-body degrees of freedom. The free-free collocation formulation begins with the deflection equation
