本文选取由余弦三角级数和多项式组成的挠曲函数,得到求解矩形悬臂板的通用方程。挠曲函数满足板的微分方程和全部边界条件、角点条件。从而得到矩形悬臂板的精确解。
In this paper, the flexion function consisting of the trigonometric series of cosine and the polynomial is selected to obtain the general equation for solving a rectangular cantilever plate. The deflection function satisfies the board’s differential equations and all boundary conditions, corner conditions. The exact solution of the rectangular cantilever plate is thus obtained.
