In this paper, the cold state simulation test is combined with vibration theory to study and analyze the influence of the surface flow pattern, the breaking wave phenomenon and the single phase flow on the depth of the wave in the shaking ladle. It is found that there is another critical state in the surface flow pattern of the single phase fluid flow in the shaking ladle, that is, the rotating stage of the saddle surface. The change of the surface flow pattern results from the superposition of different waves. The critical state in the process of the shaking ladle’s motion is attributed to the resonance phenomenon, when the frequency of the eccentric rotational shaking ladle is same time as the natural frequency of the liquid solid system. With shaking ladle inner water phase height increases, the critical speeds of the critical state increases, namely with the increase of water phases height, the natural frequency of the liquid solid system also increases.
