纵筋环肋圆柱壳结构理论与试验研究

Experimental and Theoretical Analysis of Ring-Stiffened Cylindrical Shells with Longitudinal Stiffeners

在对纵筋环肋圆柱壳结构进行理论分析的基础上,建立了该结构的力学和数学模型,得出计算公式。采用理论设计公式和有限元仿真计算设计一个大比例的舱段模型,并对该模型进行外压试验。通过对理论计算结果、有限元仿真计算结果和试验数据进行对比分析,认为环肋纵筋结构能显著提高结构的承载能力。

The theoretical analysis of ring-stiffened cylindrical shells with longitudinal stiffeners was presented.A large-scale section model was built by theoretical and FEM.And the pressure test of the steel section model was implemented.The results of theoretical and FEM model were compared with experiment,and they show that the ring-stiffened cylindrical shells with longitudinal stiffeners can significantly improve the ultimate bearing capacity of pressure hull.
