摘要:针对圆锥嵌套式Wolter?I型X射线聚焦望远镜镜片装配过程，基于Abaqus有限元软件建立了三维自适应一体化建模和仿真算法流程。利用Python语言结合Abaqus脚本接口进行二次开发，提出自适应建模仿真算法，并可精确获取不同工况下镜片的应力分布、面形偏差分布等结果。同时，在此基础上进行图形用户界面（GUI）二次开发，形成了可操作性更好的插件，大大提高了仿真效率和精度，节约了实验和人工成本。仿真结果给出了理想的镜片厚度及最佳装配载荷，并给出了更合理的面形偏差的评估方法，为光路分析以及指导实际装配过程提供了重要的理论依据。



Abstract:In this paper, based on finite element software Abaqus, a three-dimensional adaptive integrated modeling and simulation algorithm is established for the mirror assembly process of a conical nested Wolter-I X-ray focusing telescope. First, using Python language combined with Abaqus script interface for secondary development, an adaptive modeling simulation algorithm is proposed, and the stress distribution and surface deviation distribution of the mirror under different working conditions is accurately obtained. Then, the graphical user interface (GUI) is developed to build a more operability plug-in, which greatly improves the simulation efficiency and accuracy, and saves experimental and labor costs. The results give the ideal mirror thickness and optimal assembly load. Finally, a more reasonable evaluation method of surface deviation is obtained, which provides an important theoretical basis for optical path analysis and guidance for the actual assembly process.
