摘要
求解两对边固支另两对边自由的板壳大挠曲问题以往常用近似方法 ,现试用解析方法将微分方程组的求解变为代数方程组的求解 ,然后再用数值方法去做近似处理。结果表明 ,这样做不仅数学力学概念清晰 。
A semi\|analytical method is usually used to solve the large deflection displacement problems of plates and shells in the case of fixed\|supported at opposite sides and free at the other ones.This paper demonstrates a new method which transforms differential equations into algebraic equations first,then the later can be solved approximately with a numerical method.By this method a high accurate solution can be achieved easily with clear mathematics and mechanics conception.
