The modal analysis to of the u-shape bellow based on ANSYS

Xinfeng Wang

Abstract

A finite element 3-D model of the bellow is put forward with the element of shell93 in the software ANSYS. The inherent frequencies and the shapes of the vibration are obtained by the modal analysis of the bellow, which are the foundation of the further dynamical analysis. Also, the graph between the values of response (displacement) and frequencies is obtained by the harmonic analysis, which indicates that the results of modal analysis are reliable.
