| 摘 要： | 本文讨论了潜艇环肋圆柱壳总体稳定性纵向失稳半波数m的问题，m取不同值，将直接影响圆柱壳临界压力值。在潜艇结构几何相关参数设计范围内，计算分析证明，总体失稳纵向半波数存在着。m≠1，此时，如还用m＝1计算，潜艇环肋圆柱壳总体临界压力值误差最大达89．3％，是一人应该重视的问题。

| Abstract: | The half wave number m of longitudinal instability of submarine ring-stiffened circularcylindrical shell is discussed in this paper. The variation of m can influence the value ofcritical pressure of cylindrical shell- Within the scope of correlated geometrical parametersof submarine strucutre, it is shown by calculation and analysis, m may be unequal to one.If m is taken as 1 in the calculation in this case, the maximum error of critical pressure ofthe shell will be 89. 3%. This is an Important problem. |
