摘要
将作者提出的样条函数线法用于筒壳的结构分析。用样条函数插值将二元微分方程组化为常微分方程组，然后利用作者研制的ＯＤＥＳ求解器ＩＶＭＯＤＥ进行求解。文中给出了样条函数线法的基本公式，最后给出的算例与已有的结果进行了比较。
The machenics analysis of shells has been followed with interest. In this paper, for strength analysis of tube shells model of spline function method of line is given. The interpolation of B-spline function comes into use for dispacements in y-axial. The partial differential eqautions is changed into ordinary differential equations (ODES). The ODES is solved by ODE solver IVMODE. The analyzed result corresponds well to the exist values.
