The parametric resonance of an axisymmetric shell-lumped weight system subjected to periodic acceleration in the radial direction is analyzed. Symmetric and asymmetric free-vibration modes of the system are derived using the free-vibration modes of the axisymmetric shell without lumped weight. The aforementioned eigenmodes are calculated by employing a conical shell finite element. Modal Mathieu equations of the system are derived, and the parametric resonance regions of the system are calculated using Bolotin's method, considering the effect of translational motion of the lumped weight in the radial direction. Also, a circular cylindrical shell with a lumped weight is experimentally investigated using a vibration table. Numerical results of the parametric resonance regions of the system show good agreement with experimental results.
