The Effect of Length on Free Vibration Response of Cantilever Beam

Abstract

The point of this study is to find the best value of frictional and structural damping constant for different length of aluminum cantilever beam when applied 30 mm initial displacement at the tip of the cantilever beam, and get the vibration response of cantilever beam. Initial displacement is used to test dynamic characteristics of cantilever beam. This article is based on cantilever beam under initial displacement. For each length of beam there are specific values of mass (frictional) damping and stiffness (structural) damping. The value of stiffness damping will decrease and mass damping will increase at increasing the length of beam.
