The Flutter of a Uniform Cantilever Wing - ASME Digital …
2021年3月9日 · The flutter speed of a uniform cantilever wing (one with a built-in root and with constant mass and stiffness characteristics along its entire span) is determined by integration of the differential equations for the wing motion. The solution is free of the dynamical approximations usually made during flutter analyses of the Rayleigh-Ritz type.
The Flutter of a Uniform Cantilever Wing | ScienceGate
It is found that a Rayleigh-Ritz type analysis, based on the fundamental uncoupled bending and torsion modes, is entirely adequate for the flutter analysis of a uniform wing. In addition to yielding a flutter speed which is in excellent agreement with the true value, the approximate method adequately predicts the wing shape at flutter.
A method is presented for the calculation of the flutter speed of a uniform wing carrying an arbitrarily placed concentrated mass. The method, an extension of recently published work by Goland and Luke, involves the solution of the differential equations of motion of the wing at flutter speed and therefore does not require the assumption of

2009年6月5日 · One of the first works in this field is the paper by Goland [7], which concentrated on the flutter speed determination of a uniform cantilever wing. He verified the flutter speed by integration of the differential equations of the wing motion. This work was then continued on a uniform wing with tip weights [8].
