中文摘要：

根据已报道的二维流固耦合数值模拟结果，建立了经缓冲橡胶整形后的单炸药条载荷模型。将炸药条载荷叠加后直接施加在圆柱壳表面，进行二维解耦模拟，得到了与流固耦合模拟基本吻合的应力结果。在此基础上，对19条炸药条加载黟265mm×380mm圆柱壳进行了三维解耦模拟，并采用相同状态的实验予以验证。结果表明，特征点应变响应吻合较好，验证了炸药条加载圆柱壳解耦数值模拟的有效性，为大量工况数值分析、提高建模和计算效率奠定了基础。

英文摘要：

According to the previous simulation results of two-dimensional fluid-structure interaction, the model of impulsive load generated by a single explosive rod and shaped by the buffer is built. Then the loads generated by multiple explosive rods are superposed and applied on the surface of the cylin- drical shell,and a two-dimensional decoupled simulation is performed. The results basically agree with those of the fluid-structure interaction simulation. Based on that,a three-dimensional decoupled simu- lation of the 525265 mm）〈 380 mm cylindrical shell loaded by 19 explosive rods is accomplished. Mean- while,the corresponding test is performed. There shows a good agreement between the three-dimen- sional numerical and tested strain histories at typical locations. These results prove the effectiveness of decoupled numerical simulation and provide a foundation for improving the modeling and computation- al efficiency in performing a large number of numerical simulations.
