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 。
In this paper,the deflection function which consists of trigonometric series and polynomail espressions are selected according to the Kirchhoff theory of thin plate.Numeri-cal esamples show that the method has the advantages of rapid convergence and high preci-sion.Therefore,this solution can be conveniently used in practical engineering.
