An experimental study was carried out in which a vertically hanged cylindrical tank partially filled with water was longitudinally excited at the center of the bottom for several water levels. The shell was made of polyester film. The theoretical value was calculated by the method of analysis derived in Part I for comparison. The critical exciting force amplitude to produce one-half subharmonic wall vibration was measured at each constant exciting frequency by gradually increasing it. For the parametric excitation boundary, reasonably good agreement is observed between experimental and theoretical results. The resonance curves of longitudinal vibration at the bottom and the transverse wall vibration were measured under the condition of constant amplitude of longitudinal exciting force. The property of the resonance curves can be explained by the present analysis.
