SELF EXCITED AEROELASTIC OSCILLATIONS

Abstract: Flutter is a kind of self excited aeroelastic oscillations which if once sets in, hardly dies off. The negative damping of wind serves as an energy feed to the system than a decay of oscillations. Flexible long span structures are affected more by all sorts of aerodynamic forces (vortex shedding, just causing buffeting, flutter etc.) than by the earthquakes. Flutter is affected by all the parameters such as structural displacements and its derivatives, wind velocity, angle of attack, density of the structure and that of air, shape, cable arrangements, Hand rails etc, a truistic mathematical model and ideali-zation is needed and therefore the approach of finite element technique to flutter is emphasized. For design purposes, it is better to avoid the possibilities of flutter by altering the shape of the deck or stiffening the structure as a whole than to design a heavier section.. The object of the work here is to present an approach to flutter and evaluation of complex eigenvalues..
