通过对光筒柱形壳极限承载力的有限元分析及其与理论计算结果的比较,检验了采用有限元法分析柱形壳结构临界载荷的合理模型,并通过对铝铸件柱形壳网格结构屈曲载荷的有限元分析,研究了加强筋网格尺寸、蒙皮厚度等对柱形壳网格结构极限承载力的影响,从而为柱形壳网格结构的优化设计提供了分析基础和有效途径。
Through the finite element analysis of the ultimate bearing capacity of the cylindrical shell of the light cylinder and its comparison with the theoretical calculation results, the reasonable model of the critical load of the cylindrical shell with finite element method is tested. The finite element analysis of the buckling load is carried out. The influence of the size of the stiffener grid and the thickness of the skin on the ultimate bearing capacity of the cylindrical shell is studied, which provides the basis for analysis and optimal design of the cylindrical shell. way.
