Abstract
This paper deals with the flutter analysis of a rectangular sheet supported by a wire in axial flow. In the flutter analysis, Doublet-Point Method based on unsteady lifting surface theory is used to calculate the unsteady fluid force acting on the sheet surface. The equation of motion of the sheet supported by a wire with tension is derived by using the finite element method. Flutter velocity and mode are examined through the root locus of the flutter determinant of the system with changing flow velocity. In this study, experiments are conducted and compared with the analytical results. The flutter velocity, flutter mode and the local work done by the fluid force acting on the sheet surface are determined. Moreover, the influence of eccentricity on the flutter velocity is clarified.
