摘要
本文采用扁壳理论对受静水压力作用下的具有纵筋加强的圆柱壳和圆柱曲板的弹性屈曲特性进行了理论分析,文中讨论了纵筋尺寸和间距变化对其弹性屈曲压力的影响,并和其他理论的计算值和实验值作了比较,结果表明本文方法是正确和可靠的。
A general analytic method is presented for the evaluation of the elastic buckling of cylindrical shells and panels with longitudinal stiffening under hydrostatic pressure. An accurate solution is obtained through direct solution in which shallow shell equations are used. The effect of the distance between stringers and size of stringers on elastic buckling are discussed. The numerical results obtained are compared with analytic and experimental ones given by other investigators. It is shown that the method proposed is fairly accurate.
