摘　　要：为提高有限元软件ABAQUS分析星管组合药柱结构完整性的效率,本文利用Python脚本语言编程,对发动机药柱的几何模型进行了参数化的建立,分析了药柱的几何尺寸对其结构完整性的影响规律,并结合发动机的装填系数、内弹道性能等因素,对装药设计提出了一些建议。本文所设计的参数化建模方法可大大减少ABAQUS研究装药结构完整性的重复性建模工作,提高分析问题的效率。In order to improve the efficiency of structural integrity analysis of star-tube grain by using the finite element software ABAQUS, the parameterized geometric model is established by Python lan- guage. The influence of the geometrical size of the column on the structure integrity is analyzed, and ac- cording to the factors such as loading coefficient and interior ballistic performance of the engine, some suggestions of grain are put forward. The parametric modeling method designed in this paper can greatly reduce the duplication of ABAQUS research on the integrity of the loading structure, and improve the effi- ciency of the problem analysis.
