摘要：
Based on the three dimensional Biot theory and the elastic theory of thin plate, the first order differential equations of a thin rectangular porous plate under harmonic excitation were established by considering the coupling effect between the solid phase and the fluid phase. Employing the extended homogeneous capacity precision integration method, transverse vibrations problem of a thin rectangular porous plate was discussed with simply supported boundary condition in two opposite edges. In the numerical examples, both the uniform force and unit point force were taken into account. Comparisons with the classic example have verified the feasibility and effectiveness of the present model. The present model was high precision, which was derived rigorously and easy to conduct various boundary conditions. It can be applied in higher frequency range than the numerical method. © 2016, Nanjing Univ. of Aeronautics an Astronautics. All right reserved.
