压力容器大开孔补强计算——压力面积法和有限元应力分析法

摘要

从理论分析和工程实例两方面时压力容器大开孔补强计算的主要方法——压力面积法和有限元应力分析法进行分析比较.结果表明,有限元应力分析法较压力面积法安全、成熟.%The primary methods for reinforcement design 6f pressure vessels with large openings are pressure area method and finite-element stress analysis method. The two methods have been analyzed with theory analysis and project example. Finally, the conclusion is that finite-element stress analysis method is more safe and mature than pressure area method.
