| 摘 要： | 该文利用ALE（Arbitrary Lagrange—Euler）算法，应用非线性动力有限元软件LS—DYNA，计算了舰船一个舱段的舷侧防护结构在水下接触爆炸载荷作用下的动态响应过程，给出了各层防护板的应力、应变、速度和位移等动态参数的时间历程，讨论水下接触爆炸载荷对舷侧防护结构的破坏效应及影响。验证了加筋板对结构的加固作用。该文的研究工作对舰船舷侧的安全防护设计具有一定的参考价值。

| Abstract: | The-ALE (Arbitrary Lagrange-Euler) algorithm and the non-linear power finite element software LS-DYNA are used. The dynamic response process of a cabin of ship broadside defensive structure subjected to the underwater contact explosion load is simulated and computed with the software and ALE algorithm. The time history of stress, strain, velocity and displacement of each defensive plate is presented, and the destruction effect and the influence of the ship broadside defensive structure subjected to underwater contact explosion load are studied from these aspects. The strengthened function of the stiffened plate structure is confirmed. The results are constructive and helpful to the ship broadside defensive design. |
