Numerical Vibration Analysis of Rectangular Beams for Different End Conditions

Abstract

In this study the vibration behaviour of rectangular beams with different end conditions i.e. for simply supported and cantilever type is determined. This behaviour is estimated for two different materials namely aluminum (Al6063L) and mild steel (304L). Initially five natural frequencies for simply supported and cantilevered conditions are found out using Rayleigh-Ritz method for both aluminum and mild steel. Vibrational behaviour of rectangular beam under different end conditions and different material properties are carried out experimentally and results are validated.
