摘要:

本文介绍用有限单元法对壳体与梁的组合结构进行静力分析的有限元程序。文中介绍了编制组合结构程序应考虑的问题及程序中所用到的公式。对于大型复杂结构形成的大型线性方程组,采用了只用内存的分块解法。用本程序计算纯壳例题,计算结果符合于解析解。计算组合结构与试验对比能满足工程计算精度要求。用本程序计算组合结构与用美国SAP5程序计算结果是一致的。

Abstract:

This paper presents a finite element program for static analysis of a shell and beam combination structure with the finite element method. The formulas used are described in the peper. A partioning solution based on the internal storage is adopted for the large linear equations generated from more complicated structure. By using this program,calculation of an example releting the pure shell problem is carried out, the results of which are in conformity with the analytical solution. Computation of the combination structure and the comparative test can meet the requirements for engineering computation accuracy.
