| 摘 要： | 基于Ｖｏｎ Ｋａｒｍａｎ模型，对受冲击压力作用的喷管堵盖计算模型进行受力分析，计算考虑到了几何非线性和材料非线性的影响，得到了冲压作用下的喷管堵盖变形和应力分析结果。并对不同升压速率情况进行了对比分析，指出了升压速率对喷管堵盖结构受力影响的重要性。

| Abstract: | Based on Von. Karman's theory, the geometrical and material non-linear analysis of SRM nozzle closure under quick pressurization is conducted. Numerical results of stress and strain fields are also taken into account. In addition, the comparing results brought about by different pressurization rates play an important part on the stress value of the colsure structure. |
