摘要
在国家973计划青年项目的支持下,大连理工大学联合北京宇航系统工程研究所,开展了计及缺陷敏感度的网格加筋结构优化方法研究,为大直径运载火箭工程网格加筋筒壳结构的创新设计提供了理论依据和方法支撑,服务国家重大战略需求。
Supported by the young 973 project, the lightweight design theory and method for stiffened thin- walled cylindrical shells with geometric imperfections are investigated by the research team from Dalian University of Technology and Beijing Institute of Astronautical Systems Engineering. The main aim of this research is to provide some references for the design of large-diameter stiffened cylindrical shells in launch vehicle, which are expected to serve for the national strategic demands.
