The dynamic characteristics of the joined spherical-cylindrical shell with various boundary conditions are investigated. The boundary conditions considered herein are free, simply supported and clamped for the cylindrical shell and the other ends are joined with a free spherical shell. The FEM analysis and experimental results are compared with the analysis.
The Flügge shell theory and Rayleigh's energy method are applied in order to analyze the dynamic characteristics of the joined shell and individual shell structure. In the modal test, the I-DEAS test module is used to calculate mode shape and natural frequencies of the joined shell structure.
