摘　　要：运用大型通用有限元分析软件ANSYS提供的APDL语言和UIDL语言对主镜进行参数化建模并提供交互界面,可以主动输入主镜几何参数和材料参数等来改变模型,并对在自重变形下的主镜背部支撑位置进行了优化分析。整个建模分析过程表明通过使用APDL语言对主镜进行参数化建模和优化分析,可以比较不同支撑点、不同材料的主镜自重变形情况,大大提高了建模速度,极大地提高了分析效率,对相关设计人员有很好的借鉴作用。Utilizes the APDL language and the UIDL language which large-scale general finite element analysis software ANSYS provides to the primary mirror carry on the parametric modeling and provide the interactive contact surface,may input the primary mirror geometry parameter and the material parameter on own initiative and so on changes the model,and to supported the position under the self-weight distortion primary mirror back to carry on the optimized analysis. The entire modeling analysis process indicated through uses the APDL language to carry on the parametric modeling and the optimized analysis for the primary mirror,may the quite different support points ,the different material primary mirror distortion situation on self-weight,enhanced the modeling speed greatly,enhanced the analysis efficiency enormously,designs the personnel to the correlation to have the very good model function.
