LNG全容罐外框架及塔梯结构有限元计算与评定

FEM Calculation and Evaluation of Outer Frame Structure and Ladder Structure in LNG Full Containment Storage Tank

针对LNG全容罐顶部外框架结构及侧面塔梯结构等,利用有限元软件ANSYS进行了详细的结构计算与分析。并根据GB 50009—2019以及GB 50017—2017标准中规定的工况和评定标准分别对外框架及塔梯结构的强度与稳定性进行了分析与比较,计算结果表明LNG全容罐顶部外框架结构及塔梯结构的安全性是满足要求的。

For the outer frame structure and ladder structure on the top and side position of LNG full containment storage tank,details structure calculation and analysis was carried by ANSYS finite element software.And according to the GB 50009—2019 and GB 50017—2017 standards specified in the operating mode and evaluation criterias,the strength and stability of the outer frame structure and ladder structure on the LNG tank were analyzed and compared.The calculation results shows that the safety of outer frame structure and ladder structure on the top and side position of LNG full containment storage tank can meet the requirements.
