Abstract

In the recent years an application of the FEM(Finite Element Method) to the solution of the dynamic behavior of a structure has become more popular. Modal analysis technique is used to determine a structure’s vibration characteristics-natural frequencies and mode shapes. This paper explains simple steps of the modal analysis simulation using ANSYS®. The Cantilever beam is taken for study and frequencies and mode shapes are obtained in the graphical environment of ANSYS. Further Theoretical natural frequencies are obtained by hand calculations and compared with that obtained from FEM.
