当前,分析设计目前已成为压力容器的重要设计方法。本文首先阐述了压力容器分析设计与常规设计的不同。然后分析设计中应力分类及其应用,最后对常规设计和分析设计进行了详细的比较,为研究奠定了基础。 At present, analytical design has now become an important design method for pressure vessels. This paper first describes the difference between pressure vessel analysis design and conventional design. Then, the stress classification and its application in the design are analyzed. Finally, the conventional design and the analysis and design are compared in detail, which lays the foundation for the research.
