“一次结构法”在薄管板换热器应力分析设计中的应用

APPLICATION OF “PRIMARY STRUCTURE METHOD” ON STRESS ANALYSIS DESIGN FOR THIN TUBESHEET HEAT EXCHANGER

北京清华大学陆明万教授等提出的一次结构概念，为灵活运用应力分类准则进行更科学、合理的压力容器分析设计提供了一种新的途径。作者以固定式薄管板换热器应力分析设计为例，阐述了“一次结构法”的应用。

The primary structure conception,proposed by professor lu wanming of Qinghua university,offered a new way of more scientific and reasonanle pressure vessel design for flexible using stress classfication criterion. The author took fixed thin tubesheet heat exchanger as an example to demostrate the application of primary structure method.
