The experimental results on the dynamic behavior of partially liquid-filled thin cylindrical shells under harmonic vertical excitation are presented and discussed. The transition phenomena which have discontinuous shift of the vibrating acceleration and the shell wall surface displacement for the shaker power are recognized. The shift is well influenced on the thickness of shell wall. Its shifted acceleration is enlarged by the thinner wall. Several spectra are observed in the response of shell wall to transition point, and their changing process are classified into two patterns. In case of larger transitional acceleration, some chaotic behaviors occur in the transition process. On the other side, principal resonance of parametric excitation is confirmed at smaller transitional acceleration.
