| Abstract: | A finite element 3-D model of the bellow was put forward with the element of shell93 in the software ANSYS. The inherent frequencies and the shapes of the vibration were 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 was obtained by the harmonic analysis, which indicated that the results of modal analysis are reliable. |
