加筋圆柱壳开孔结构强度分析

加筋圆柱壳开孔结构是潜艇典型耐压船体的主要结构形式之一,如何避免在开孔周围造成应力集中,即开孔结构补强是工程中特别关心的问题。在设计过程中,因为要多次建模分析,会导致设计分析效率变低,所以开发了加筋圆柱壳开孔结构的参数化建模分析程序。基于参数化建模分析程序,讨论了多参数对于开孔周围应力集中的影响。

Strength analysis of stiffened cylindrical shell with a circular opening

The stiffened cylindrical shell with a circular opening is one of the main typical pressure hull structures used in submarine. How to avoid the stress concentration around the opening is a particular concern in the project. In the design process, a number of modeling analysis will lead to low efficiency of design analysis. So, the parametric modeling and ana-lysis program of stiffened cylindrical shell with opening structure is developed. Based on parametric modeling and analysis program, the influence of multi parameters on the stress concentration around the open hole is discussed.
