摘要: In this paper, the authors investigate axisymmetric vibrations of a vessel with variable thickness composed cylindrical shell and two circular plates as its lids. They obtain Lagrangian expressed by quadratic forms unknown boundary values frequency equations from minimum condition Lagrangian. Effects variations shell, length etc.upon natural frequencies mode shapes are clarified in discussions numerical results.
