摘　　要：根据大型对日定向装置的结构特点和受力特性,调整传力结构,充分利用纤维增强复合材料结构的可设计性,开展优化设计。在保证高刚度和轻量化的同时,克服结构大开口带来的承载能力不足,设计出结构质量与承载比仅为5.2%,集舱段和壳体功能于一体的大型对日定向装置复合材料主承力架结构。建立有限元模型,分别采用Tsai-Wu和最大应变2种纤维增强复合材料的强度失效准则,对其进行校核。开展静力试验,采集应变等信息,与有限元仿真分析结果展开对比。结果表明:其整体趋势一致,顺利通过试验考核。According to the structural and mechanical characteristics of large-scale solar-oriented devices,the optimized design is carried by optimizing the force transfer structure and making full use of the designability of fiber reinforced composite materials.In order to ensure the demands of high stiffness and lightweight and overcome the insufficient bearing capacity caused by large opening structure,the main bearing frame products with the weight-tobearing ratio of only 5.2%are designed for large-scale solar-oriented devices.It has both the function of the spacecraft module section and the function of the mechanism shell.The finite element analysis model is developed by using two strength failure criteria,i.e.,Tsai-Wu and maximum strain.Static tests are performed,and the information such as strain is collected.The obtained data are compared with the finite element analysis results.The results show that the overall trend is consistent,which verifies the feasibility of the present design.
