Basic Study on Vibration Properties of the Laminated Cantilever Beam

Abstract

We performed static and dynamic experiment and their analysis for the laminated cantilever beam which consists of 2 or 4 layered beams in order to find frictional influence on their properties. On static experiment and analysis we found that frictional force between layered beams influences on the stiffness. Loading the laminated cantilever beam decreases its stiffness. Increasing clamping force, changing point of stiffness moves toward the hard stiffness. On dynamic experiment and analysis, we found that frictional force influences on vibration properties. Making impact force strong, peaks of compliance and their frequencies decrease. 4 layered beams produce greater change than 2 layered beams.
