摘要
基于 Kirchhoff薄板理论 ,提出双三角级数形式的挠度函数 ,求得了两对边固定两对边自由矩形板的精确解 ,计算结果表明 :这种解法收敛速度快 ,计算精度高 ,易于工程应用。
In this paper,the deflection function which consists of trigonometric series and polynomial expression is selected according to the Kirchhoff theory of thin plate.Numerical examples show that the method has the advantages of rapid convergence and high precision.Therefore,this solution can be conveniently used in practical engineering.
