摘要
用可靠性技术,对压力容器开孔和补强结构的可靠度计算方法作了介绍,对影响开孔和补强可靠度的因素作了分析,达到改善补强的目的。对现行设计规范上的一些开口和补强结构的可靠度作了验算。
Deals with the calculating methods of the reliability on pressure vessel's openings and reinforcements by reliability techniques. It also analyses various factors affect- iag the reliability and calculates the reliabilities of some structures in designing standards in (effect. Some useful data are presented.
