Free Vibration Analysis of Cantilever Beam of Different Materials

Nirmall.T | Dr. Vimala.S

Abstract: All materials possess sure amount of internal damping which manifested as dissipation of energy from the system. This energy in a vibratory system is either dissipated into radiated away from the system. To study and find the damping in structures made of different materials aluminum, brass, mild steel are still remains as a big task. The main objective of this study is to estimate the natural frequency of aluminum, brass and steel by free vibration analysis experimentally & verify theoretically. Cantilever beam (450mm x 30mm), (400mm x 25mm) and Tapered cantilever beam (450mm x 23mm), (400mm x 20mm) of size are prepared for experimental purpose of free vibration analysis of beams made with different materials such as aluminum, brass and mild steel. The natural frequency of the beams obtained from experimental & theoretical methods will be compared with harmonic analysis using ANSYS software.
