Determination of modal characteristics of cantilever beam

Abstract

Modal analysis is a method to describe a structure in terms of its dynamic properties such as natural frequency, damping and mode shapes. These parameters are essential in engineering design and analysis. In this work, Theoretical modal analysis of cantilever beam using Euler-Bernoulli beam theory and FEA modal analysis of cantilever beam in ANSYS Workbench, have been performed to find its natural frequency and mode shapes. Finally, FEA results are compared with analytical results and a good agreement was found between modal parameters.
