摘要
在肋环型球面壳的整体稳定分析中,完全不考虑或者完全考虑铺板作用的常规简化方法,均存在着不同程度的缺陷。详细分析了肋环型球面壳的结构特点,剖析了常规简化方法缺陷产生的原因及后果,提出了一种改进方法,即计入沿小次梁方向40倍～60倍铺板厚度对应的板宽对整体结构的刚度贡献,并给出了该方法的具体操作途径。
Both the two general simplified methods of the ribbed-type spherical shell＇s stability analysis to count all the armor plate or not have different degree defects. The special structure and causes and consequences are detailed analysed, then a new method to consider the 40-60 multiple of the armor plate＇s thickness is put forward, including the operational means.
