This report describes the dynamic behavior of partially liquid-filled thin cylindrical shells which are subjected to vertical excitation. In case too much liquid is contained, the structure is often damaged. The exciting acceleration, the surface deformation and the generated sound, as dynamic behavior of the shell made of a Lummiror polyester sheet, are treated experimentally. The acceleration and the deformation vary with discontinuity as if the transition phenomena occurred. The transition is caused in the lower frequency region at the longer cylinder effective length, that is, with the increased liquid potential head. The frequency response of the shell wall is observed as several spectra which change due to transition. The acoustic spectra of sound generated from the shell depend on the wall response. There are correlations between both characteristics. Therefore, the response condition of the shell wall can be predicted by the acoustic spectrum.
