Limit cycle oscillation of a fluttering cantilever plate


Journal Article

This is the first such study for a plate with some edges unsupported. Previous work has dealt with all edges supported. Von Karman theory for a plate and quasisteady, supersonic aerodynamic theory have been assumed. A Rayleigh-Ritz approach has been used to solve for the nonlinear oscillation of a fluttering plate. The lengthto- width ratio of the cantilever plate Has a significant effect on the flutter vibration. For small length-to-width ratio, the dominant chordwise modes are translation and rotation; however, higher bending modes must be included to obtain an accurate prediction of the flutter onset and limit cycle oscillation. For large length-towidth ratio, significant chordwise bending is apparent in the flutter motion, with the trailing edge area having the largest motion. © 1991 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
