摘　　要：本文建立了纵横加肋圆柱壳结构的有限元应力分析的力学模型,论证了纵骨尺寸、纵骨间距对壳体应力状态的影响。提出了一种等效各向同性壳的近似解析公式,验证了近似公式的适用性。为开展纵横加肋圆柱壳的结构设计打下了良好的基础。A mechanical model with finite element stress analysis of longitudinal-transverse stiffened cylindrical shell is set up. The influence of change of longitudinal frame size and span on shell stress is expounded. A series of approximate analytical formulas of equivalent isotropic shell are presented. The suitability of approximate formulas is verified. A very good base is made for designing the structure of longitudinal-transverse stiffened cylindrical shell.
