摘　　要：作为飞机结构的主承力构件,加筋壁板结构的强度校核一直是设计人员重点关注的问题之一。为降低该项工作的复杂性和重复性,在国产CAE软件平台HAJIF基础上,研发了金属加筋壁板结构强度校核软件,实现了强度校核工作的流程化和自动化。软件采用统一分层架构思想,依次研发了独立的前端界面、强度计算、工作应力提取、结果后处理等核心模块,并与HAJIF软件的前后置有机融合,实现模块之间的统一调度。验证算例表明,该软件能够满足飞机加筋壁板典型分析情况校核要求,符合强度校核流程和使用习惯,明显提高了强度设计与分析人员的工作效率。As the main bearing component of the aircraft structure,the strength check of the stiffened panel structure has always been one of the key concerns of designers.In order to reduce the complexity and repeatability of this work,on the basis of the domestic CAE software platform HAJIF,the strength check software for the metal stiffened panel structure was developed,which realized the process and automation of the strength check work.The software adopted the idea of a unified layered architecture,and successively developed independent front-end interface,strength calculation,work stress extraction,result post-processing and other core modules,and organically integrated with the front and rear interface of the HAJIF software to achieve unified dispatching between modules.The verification example shows that the software can meet the check requirements of the typical analysis situation of aircraft stiffened panels,conform to the strength check process and usage habits,and significantly improve the work efficiency of strength design and analysts.
