Vibration Analysis on a Thin Walled Structure

Abstract

A vibration analysis performed on thin walled open beam section. The influence of the vibration is studied for different thickness and different critical load conditions. A FEM model is applied to the thin wall sections like beams. For the different young’s modulus, critical load and thickness of the flange the mode shapes are analyzed. The free vibrations of the channel unsymmetrical thin-walled beam of length 80, breadth of the flange is 37.81e-3, thickness of the flange, over all lengths of the flange at λ = (7.5, 10,12.5,15,17.5,20), for e= 10,20.3040,G= rigidity of modulus also been analyzed..
