通过对弹性基础梁的复杂弯曲进行塑性极限状态分析,得到了表示潜艇加肋圆柱壳在静水外压下,壳板轴对称变形的极限状态判据和极限载荷的计算方法。并用模型试验对计算方法进行了验证。
Through the analysis of the plastic limit state of the complex bending of the elastic foundation beam, the limit state criterion and the ultimate load calculation method for the symmetrical deformation of the shell plate under the hydrostatic external pressure are obtained. The model test is used to verify the calculation method.
