商业结构分析软件包ANSYS 9.0提供的可靠性分析工具相对易于使用，并且可以快速获得解决方案。然而，该工具不能保证可靠性分析的结果，因为它只能提供故障概率的概要趋势，而不能给出设计者所需区域的故障概率的准确数值。独立的商业可靠性分析代码NESSUSS 7.0也存在问题，因为它可能不一定收敛，并且可能浪费计算时间，因为必须对设计变量进行不必要的重复结构分析，这些设计变量对被设计对象的结构完整性没有什么意义。本文提出了一种设计方法和一个软件模块，它可以弥补目前这些商业软件包中的不足之处，作者已经开发出，并在本文中。本文介绍了如何应用的方法和软件模块的设计和制造的加筋压力容器，它可以安装在6000米级深海无人水下航行器。
The reliability analysis tool provided with the commercial structure-analysis package, ANSYS 9.0, is relatively easy to use and allows solutions to be rapidly obtained. However, the tool cannot guarantee the results of the reliability analysis since it can only provide an outline tendency of the probability of failure without giving an accurate numerical value of the probability of failure at the regions that a designer requires. The independent commercial reliability analysis code, NESSUSS 7.0, also has problems in that it may not necessarily converge and can waste computation time from having to undertake unnecessary repetitive structure analyses for design variables that have little significance to the structural integrity of the object being designed. A design methodology and a software module, which can make up for the current deficiencies in these commercial packages, have been developed by the authors and are presented in this paper. This paper describes how the methodology and the software module were applied to the design and manufacture of a stiffened pressure vessel, which can be mounted on a 6000 m class deep-sea unmanned underwater vehicle.
