摘要
本文应用正交函数系级数展开法分析结构的理论，以带附加补充项的Ｆｏｕｒｉｅｒ级数作为挠度函数模式，求解了Ｗｉｎｋｌｅｒ地基上自由边矩形板的弯曲问题。文中给出了算例，其载荷形式是较难处理的角点集中力形式。
in this paper, through structure analysis by means of orthogonal function system expansion, a solution for the bending problem of the rectangular plates with free edges on Winkler foundation is reached. The Fourier series with additional terms is used as the expressions of deflection function and the numerical example is presented.
