| 摘 要： | 耐压圆柱壳体通常采用环肋加强以提高其在静水外压作用下的结构稳定性.文中在理论分析和实例计算的基础上对多种型式肋骨加强的耐压圆柱壳体的稳定性进行了比较,比较结果表明:在肋骨用材总量相同的情况下,通过合理选择肋骨型式或合理设计肋骨尺寸,使其面内惯性矩增大,可以较大幅度地提高耐压圆柱壳体的总体失稳压力;相邻两肋之间净距离较小的肋骨,可以较大幅度地提高肋间壳板的稳定性.

| Abstract: | The pressurized cylindrical shell is generally ring-stiffened in order to enhance its buckling resistance under uniform hydrostatic pressure.In this paper,comparisons were done based on the theoretical analysis and calculation on the buckling of cylindrical shell ring-stiffened by manifold stiffeners.The results show that the global stability of the cylindrical shell can be improved because the moment of inertia is greater by means of rational selection of its model or rational design of its dimension.The local buckling load of the cylindrical shell increases if the cylindrical shell ring-stiffened by the stiffener and the net spacing of adjacent that is shorter than others. |
