Modal Analysis of Beams Using Finite Element Methods

In this development, a modal analysis of free-free and fixed-free beams undergoing free vibration is investigated in Ansys APDL (15.0) based on Finite Element Analysis (FEA) and analytically using Euler-Bernoulli beam theory. In addition, the natural frequencies for the free-free beam are found to be much higher than those of the cantilever beam and the natural frequencies enlarge by increasing the mode number in both of the cases.

Abstract

In this development, a modal analysis of free-free and fixed-free beams undergoing free vibration is investigated in Ansys APDL (15.0) based on Finite Element Analysis (FEA) and analytically using Euler-Bernoulli beam theory. In addition, the natural frequencies for the free-free beam are found to be much higher than those of the cantilever beam and the natural frequencies enlarge by increasing the mode number in both of the cases.
