摘要: 复合材料作为新一代轻质、高强度材料,已经在航空航天制造行业中被大量应用。对于整体复合材料油箱的结构设计,其核心在于满足强度要求下的密封设计。本文首先根据气密性要求,采用ABAQUS有限元分析软件对整体复合材料应变分布进行分析,优化密封结构设计,然后根据设计要求制造复合材料油箱部件,最后对组装好的整体复合材料油箱进行验证。结果表明所设计的整体复合材料油箱能够完全满足气密性保压要求,同时也能够满足耐油性试验要求。

Abstract: Composite materials, as a new generation of lightweight and high-strength materials, have been widely used in the aerospace manufacturing industry. In terms of the structural design of composite fuel tanks, the core issue relies on the seal design under the strength requirements. In this paper, firstly, according to the air impermeability requirement, ABAQUS finite element analysis software was used to analyze the overall composite strain distribution, and then the seal structure design was optimized. After that, the composite fuel tank components are manufactured according to the design requirements, and finally the assembled overall composite fuel tank was verified. The results show that the designed composite fuel tank can fully meet the requirements of air impermeability pressure test and the oil resistance test as well.

Key words: composite fuel tank manufacturing, finite element analysis, seal structure design, air impermeability test, fuel resistance test
