| 摘 要： | 采用符拉索夫计算法计算武器命中后的舰船浮态和外载荷的变化，以Kollbrunner-hajdin改进的薄壁梁理论为基础，用迁移矩阵法计算鱼雷命中舰船主要船体后的结构应力，考虑了某些舰船结构不对称性和破口引起的不对称性造成的弯扭耦合及不同剖面的协调问题，并以某非对称结构舰船为计算模型进行了数值计算分析，找出正应力和剪应力随不同破口部位及尺寸的变化规律，与命中前完整 应务进行了对比，从而为舰船破损后的剩余强度提供依据。

| Abstract: | Presents the calculation of variation of floating parameters and external loading of torpedo damaged warship structure under the waterline using Vlasov's calculation method with a large surface warship with asymmetry structure as a model, the computation of the stresses of damaged warship hull structure using tranfer matrix method based on the modified Kollbrunner_Hajdin thin_wall beam theory,considering combination of bending and torsion caused by structure and damage asymmetry,to establish the law governing the variation of normal stresses and shear stresses of damaged warship varying with position and dimension of damage,and their comparison with structure stresses of integrated warship to provide the basis for study on residual strength of damaged warship. |
