| 摘 要： | 对静水压力下环加肋圆柱壳弹性失稳临界载荷现有计算方法进行了比较和计论。采用各种方法，对Ｔ形截面和槽形截面环助圆柱壳总体失稳临界压力进行了计算，结果表明，现有解析公式都未能综合考虑加肋壳体失稳临界压力的各个影响因素。为此，提出了改进的解析公式和半解析数值方法。

| Abstract: | A comparison is made among current calculation methods for the buckling of ring-stiffened cylindrical shells under hydrostatic pressure. The buckling pressures of cylindrical shells stiffened by T-shaped and hat-shaped stiffeners are calculated using these methods. The results show that current formulas fail to consider comprehensively every factor affecting the buckling pressures. Thus, the formula and semi-analytical method which consider more factors are proposed. |
