Dynamic characteristic of stiffened thin plate structure is superior to that of conventional thin plate structure, but it continues to suffer from the problem of less damping and large vibration sound radiation. The vibration noise of thin plate structure can be effectively reduced by damping treatment. In this paper, the dynamic model and eigenvalue equation of orthogonal thin plate structure with damping are established. Aiming at the rectangular reinforced thin plate with simply supported boundary, the influence of damping thickness and damping distribution on the natural frequency is studied. The relationship between damping thickness, damping distribution, position of excitation point and vibration response characteristics is obtained by vibration harmonic response analysis, and the topological structure of damping layer distribution is analyzed and calculated.
