Flutter analysis of a flat plate suspended by wires

Abstract

This paper deals with the flutter analysis and experiments of a flat plate suspended by wires. In the flutter analysis, Doublet-point method based on unsteady lifting surface theory is used to calculate the unsteady fluid force acting on the plate surface. The theoretical model of the plate suspended by wires is derived by using the Lagrange equation of motion. Moreover, flutter velocity and frequency are examined through the root locus of the flutter determinant of the system with changing flow velocity. The influence of the suspending angle on the flutter velocity, frequency, and mode are clarified.
