| 摘 要： | 各向均匀外压力作用下的环肋圆柱壳，在总稳定方面会出现异常特性，例如，其稳定性不能正常地随其刚度的增加而增大。本文根据环肋圆柱壳在三种外力状态下（仅受轴向均匀外压，仅受横向均匀外压和各向均匀外压），总稳定性随几何参数变化的规律，从理论上详细说明了异常特性的实质是仅受轴向外压的特性，最后用模型实验结果证明理论分析与研究的正确性。

| Abstract: | In the calculation of the ring stiffened cylindrical shell overall stability for certain structure element combination,some abnormal features(e.g.its stability does not increase properly with the increase of its rigidity etc.)are found.This paper gives a detailed theoretical explanation of the regularity of the overall stability of the ring stiffened cylindrical shells with various geometrical parameters under three kinds of external pressure respectively(i.e.under only longitudinal,under only circumsfe rential and under uniform external pressure).and points out that the abnormal features of the overall stability of the ring stiffened cylindrical shells are substantially and only subjected to longitudinal pressure.The above mentioned study is justified by model experiments. |
