摘　　要：提高水下结构在受到爆炸冲击后的抗冲性的一个重要方法是采用性能优良的抗冲击材料,为了研究橡胶元件对水下结构的抗冲击性能的影响,利用ANSYS有限元分析软件,建立带有橡胶元件的钢板与不带有橡胶元件的钢板的流固耦合有限元模型,以经验公式得到的冲击波激励为输入,通过有限元仿真得到的钢板的响应的对比结果来说明,橡胶元件可以有效地提高水下结构的抗冲击性能。One important approach to improving the impact-resistance performance of the structure under water in explosion collision is to use the fine material of impact-resistance performance. To research how the rubber component influence the structure which is impacted under water. We utilize the FEM software ANSYS to set up two fluid-structure coupled FEM model. One has the rubber component, and the other has not. Load is the impact wave from the experimental formula. We contrast the two results from the two different models in order to illustrate that rubber component can improve the resisting impact-performance of the structure under water. Effectively.
