结合临近空间环境特点,致力于发展低能耗、高效率的能源控制系统的目标,开展了临近空间飞艇新型超压加筋结构布局优化设计技术研究。本文以某型临近空间飞艇为例,提取其中能源控制系统某一功能部件,建立南瓜形加筋结构的近似模型,并利用多学科优化软件Isight集成Nastran对加筋结构进行布局优化设计;然后将优化结果制造加工出试验件,进行地面原理性超压试验,最终对其进行了爆破试验,试验结果表明加筋结构的极限承载能力与爆破试验值基本相符,误差仅为3.3%,完全满足工程精度要求,达到了预期目的。 Combining with the characteristics of nearby space environment, we are committed to the goal of developing energy control system with low energy consumption and high efficiency, and research on the optimal design of the layout of the new overpressure reinforced structure near the spacecraft. In this paper, taking a certain type of spacecraft as an example, one of the components of energy control system is extracted and an approximate model of pumpkin-shaped stiffened structure is established. The optimized design of stiffened structure is carried out by using Isight Nastran integrated multi-disciplinary optimization software. Then, The test results show that the ultimate bearing capacity of the reinforced structure is basically consistent with the burst test value, the error is only 3.3%, fully meet the engineering Accuracy requirements, to achieve the desired purpose.
