摘 要: | 提出了一种正交正放网格圆柱形壳的内力分析方法,列出了杆件内力与位移的计算公式。为了简化计算,取两个方向杆件的重心轴在同一柱面上,把它当作薄壳的中曲面。又由本文中的假定条件,使各向异性壳转换为各向同性壳,从而使计算简化。

The Stress Analysis of the Anisotropic Orthogonal Cylindrical Gridwork Shell |
| |
Abstract: | This paper is aimed at the stress analysis of the anisotr-opic orthogonal cylindrical gridwork shell, formulating the formulas for calculating The internal forces and the displacements of the members.For the sake of simplicity, some assumptions are made, The centr-oidal axes of the members in two directions lie on the same cylinder, choosing it as the middle surface of the shell. A simplified process in the calculation is taken into account, the anisotropic gridwork shell can be transformed into the isotropic shell. |
