Abstract:
Based on the RayleighRitz method, the vibration of circle plate with a boundary fixed in liquid is studied and the vibration frequency of circle plate is given. The vibration of circle plate submerged in water is simulated by the finite element model of ANSYS. At last, the diagram between the normal modes and the vibration of frequency are drawn by using MATLAB. The result shows that the frequency of circle plate in the water is less than that of the air, and the deeper of the water, the lower of the frequency.
