摘要
本文提出样条高斯配点法解算加劲板壳的静力问题。文中应用双三次 B 样条函数作为试函数,由能量原理导出系统方程,在积分式中,使用了高斯分片积分配点技术。文末给出若干数值算例,计算结果,精度满意。
This paper presents a spline Gauss collocationmethod to analyze the static problems of stif- fened plates and shells with various constrainted conditions.The bicubic B splines are used as coordinate functions to formulating the problem based on energy principles using the technique of piecewise Gause integration collocation.Some examples are solved in the paper.The accuacy of the results is compared with those calculated by other methods and found to be in good agreement.
