摘要
为了掌握超大立式钢制储罐结构的静力特性,文中基于势流理论,引入流固耦合单元和接触单元,利用有限元软件ADINA建立15万立方米超大钢制储罐体系三维有限元模型,进行储罐结构在不同充水高度下的静力分析,获得储罐罐壁结构不同高度处的环向和轴向应力及分布规律,通过与试验结果进行对比,二者吻合较好,验证了ADINA有限元建模方法的合理性。最后给出了超大立式钢制储罐罐壁的应力云图和设计建议,为进一步开展储罐的静动力非线性分析奠定基础。
In order to master the static characteristics of the super vertical steel storage tank structure,based on the potential flow theory,the fluid structure coupling element and contact element are introduced,and the overall FEM of 150 thousand m3 extra large vertical steel storage tank system is established by using the finite element software ADINA.The static analysis of the tank structure under different water filling height is carried out,and the circumferential and axial stress and distribution at different height of the tank wall structure are obtained.The results show that simulation results are in good agreement with the experimental results,and the rationality of ADINA finite element modeling method is verified.Finally,the stress nephogram and design suggestions of the wall of the super vertical steel tank are given,which lays the foundation for the further static and dynamic nonlinear analysis of the tank.
