| 摘 要： | 针对工程实践中常见的一种板厚沿单方向线性变化的变厚度薄板,本文借助於无穷级数方法,将变厚度薄板复杂的弯曲问题的控制微分方程转化成一系列等厚度薄板形式的控制微分方程,进而应用边界元法进行求解,以获得变厚度薄板弯曲问题的近似解。

| Abstract: | In this paper, acommon thin plate of variable thinckness in practical engineering has been analysed by Boundary Element Meth- od(BEM). With the help of power Series Method, the complex control differential equation of thin plate of variable thinckness is resolved into a series of equations of equi-thinckness plate. Then BEM is used repeatedly to solute these equations, so that the result of thin plate of variable thinckness can be obtained. |
