Aeroelastic vibration of a rectangular sheet under forced excitation in uniform flow

Abstract

This paper describes vibration characteristics of a cantilevered flexible sheet under forced excitation (motion excitation) in uniform flow. A theoretical model of the sheet subjected to forced excitation in fluid flow using the Doublet-point Method based on the unsteady lifting surface theory is developed. Frequency response (amplitude ratio between the excitation displacement and displacement of the sheet with changing excitation frequency) is investigated theoretically.
