摘要：
An improve Fourier-Bessel series method and the Rayleigh-Ritz method are proposed to analyze the free vibration of circular plates with elastically restrained boundary conditions. The vibration displacement is expressed as the superposition of Fourier-Bessel series and auxiliary series functions in the form of the product of polynomial function and cosine series expansion. The use of these supplementary functions is to overcome the discontinuity problems encountered in the displacement partial differentials along the edge. Then the Rayleigh-Ritz method can give the matrix equation of the circular plate, and all the frequency parameters can be easily obtained by solving this matrix equation. The eigenvalues are the nature frequencies and the eigenvectors are the modes of the plate. Finally the numerical results and the comparisons with FEA as well as those reported in the literature are presented to validate the correctness of the method. ©, 2015, China Ship Scientific Research Center.
