| 摘 要： | 圆柱形围壁加强的球壳开孔是一种组合回转壳结构.该文采用与回转壳相对应的弹性基础梁理论方法进行求解.该方法较壳体理论(或扁壳理论)求解更方便,并能适应较复杂的加强结构和受力状态,同时获得较多的计算结果,该方法计算结果与有限元方法计算结果基本吻合.

| Abstract: | Based on the theory of beam on an elastic foundation,an analytical method for stresses of opening in spherical shell is developed in this paper.Rather than the normal shell theory(or theory of shallow shell),this method can be more conveniently applied to complicated stiffened structure subjected to different load,and obtain more desired results.Analytical results are satisfied with results by FEM. |
