中小型LNG船C型罐温度场分析及鞍座设计选择

摘要

Taking QIYUAN LNG 28 000 m3 LNG carrier as the research object, a 3D FE model was established in ANSYS to study the steady state temperature field of the cradle and surrounding hull structures of the type C independent liquid cargo tank.According to the operating norm for LNG ship, regulation requirements of the classification society and the IGC standard, the structural configuration of cradle, the steel grade and thickness of the hull structure were determined.%以启元号28 000 m3 LNG运输船为研究对象,基于ANSYS有限元软件,建立该船三维有限元模型,计算分析该船C型独立液货罐鞍座及其附近船体结构的稳态温度场;结合实船运营基准以及船级社、IGC标准要求,确定鞍座的形式与船体结构的钢板等级和厚度.
