| 中文摘要: |
| 本文研究了两斜交圆柱壳的边界元法。提出了用板的基本解叠加级数形式的修正项构成圆柱壳的基本解,提高了计算精度,缩短了计算时间。对区域积分进行特殊处理,从而避免了内部网格的划分,大大减少了数据准备工作量和占机内存。并编制了FORTRAN计算程序,进行了数值计算。 |
| 英文摘要: |
| In this paper, the Boundary Elment Method (BEM) is applied to two oblique intersecting cylindrical shells. The fouadmental solution of plate superposing triangle series solution is used as that of cylindrical shell, as a result of which numerical accuracy is improved and the computing time is saved. Area intergration is particularly treated, and the discreteness of internal mesh is avoided, greatly reducing the work load of preparing data and the storage of computer. The FORTRAN program is designed and numerical example is gived. |
