基于有限元分析的大型油罐大角焊缝结构研究

Research on Large Fillet Weld Structure of Large-scale Oil Tank Based on Finite Element Analysis

《API 650钢制焊接石油储罐》设计规范适合较大型储罐的设计,但其内容中没有大角焊缝处的受力情况,因而难以实现结构优化设计。因此,对大型储罐大角焊缝结构设计技术进行研究时,可以参照API650《钢制焊接石油储罐》设计规范进行初步设计后,再使用有限元分析工具,利用参数化分析方法实现结构优化设计。

The design specification of the API 650 Steel welded Oil Storage Tank is suitable for the design of large-scale tanks, but there is no stress on the large fillet weld in the content, so it is difficuh to a- chieve structural optimization design. Therefore, when researching the design technology of large fillet weld joint structure of large storage tank, it can refer to API 650 Steel welded Oil Storage Tank design specification for preliminary design, then use finite element analysis tool to realize structural optimization design by using parametric analysis method.
