摘要:船用液化天然气储罐作为移动式压力容器,在运输过程中不仅承受静载荷,并且还承受一定惯性载荷的作用。相比传统的常规设计计算,使用有限元方法对于液化天然气储罐的结构强度分析将会更加准确方便。文中使用ANSYS软件对液化天然气储罐建立有限元模型,对于惯性载荷作用下的储罐进行了数值模拟,对于受到应力集中的局部进行应力分类和安全评定。仿真结果对于液化天然气储罐的设计制造提供参考和依据。
As transportable pressure vessel,LNG storage tank used in ships bears not only the static load,but also inertia force in the transport process.Compared with the traditional calculation of conventional design,the use of finite element method for analysis of structural strength of LNG storage tank will be more accurate and convenient.In this paper,the finite element model is established for LNG storage tank using the ANSYS software,stress analysis was done for tank inertial load,stress classification and safety assessment are made for the parts of stress concentration.Simulation results provide the reference and basis of design and manufacture of LNG storage tank.
