摘要
由板的基本方程,将位移和荷载沿环向展开为傅里叶级数,可得用傅里叶级数及多项式表示的环形板和直边简支的扇形板的级数解.还用富里叶级数处理沿径向分段连续荷载的问题.
Based on the governing equation of plate deformation the displacements and load are ex-pressed in Fourier series in azimuthal direction, the solutions of annular and sector plates with straight boundary simple supported are expressed in the product of Fourier series and polynomials. The Fourier series are also used for dealing with the prob-lem of the sectional continuous load along radial di-rection.
