    RESEARCH ON FREE VIBRATION CHARACTERISTICS OF THIN PLATE STRUCTURES BASED ON IMPROVED FOURIER SERIES by WU Baoning, LIU Fang, DONG Rong, NIE Shaoqing, LIU Yafei

    Published 2025-06-01
    “…Aiming at the problem of structural vibration modeling and characteristic analysis of rectangular sheets under arbitrary boundary conditions, an improved Fourier series method was proposed.Based on the Rayleigh-Ritz method, the allowable function of vibration displacement of thin plates was expressed as a linear combination of double Fourier cosine series function and auxiliary series function, which effectively avoided the possible discontinuities or singularities of the traditional Fourier series at the boundary. …”
