船用LNG带冷箱燃料罐强度仿真分析

Strength Simulation Analysis of Marine Fuel Tank with Cold Box on LNG

运用有限元软件建立某船用LNG带冷箱燃料罐有限元模型,并对燃料罐在运输过程中受货物载荷、惯性载荷作用下的筒体、封头、内外容器间的支撑结构以及鞍座等结构的应力水平进行具体强度分析,并与规范进行比较分析,对其是否满足行业规范进行确定,同时为后续研究提供标准。

The finite element model of marine fuel tank with cold box on LNG is established by finite element software.The stress levels of the cylinder, the head, the support structures between inner and outer container, the saddle and other structures under the cargo load and inertia load while transporting are analyzed.Comparing with the trade standard to determine whether the stress level meets the standard requirements, the standard is provided for following research.
