| 摘 要： | 基于显式非线性动力学分析程序ABAQUS,对水下圆柱壳受到水下爆炸冲击作用下的非线性动态响应进行研究。详细计算不同简化模型受到水下爆炸冲击波作用下的响应并与完整模型的结果进行对比。研究结果表明,用圆柱壳结构的部分模型代替完整模型,可以得到较为满意的计算结果。

| Abstract: | Based on the explicit finite element code ABAQUS, non-linear dynamic response of an immersed cylinder subjected to underwater explosion was analyzed. The response of different simplified models subjected to underwater explosion and the comparisons with the results of the whole model were comprehensively discussed. The results show that satisfactory simulation can be obtained by establishing a part of the model of the cylinder instead of the whole model. |
