该文针对环境一号 C 星构架反射器展开驱动部件易出现疲劳、破坏等问题，开展了面向可靠性的驱动部件优化设计。基于驱动部件失效模式及其影响分析(FMEA)，获得导致部件失效的主要失效形式为关键弹簧零件(扭簧和涡卷弹簧)的应力松弛和冲击破坏失效。对失效模式下扭簧和涡卷弹簧原型进行了特性测试、可靠度分析，提出可行的可靠性增长措施，并进行优化设计。对比优化前后的弹簧可见，优化可靠且有效。研究对该类可展开天线反射器的设计分析具有重要的参考价值。

Expansion-driven HJ-1-C satellite components are prone to fatigue and fracture;thus, a reliability study on the optimal design is performed. According to the Failure Mode and Effects Analysis (FMEA) of the components, the main failure modes are stress relaxation and impact breakage of the torsion and scroll springs. On the basis of the failure modes, a prototype spring is tested, and the relative reliabilities are calculated. Then, reliability measures are proposed, and the design optimization of the springs is carried out. The improvements introduced by the prototype spring are indicative of the effectiveness and reliability of the design optimization process, which can help design and analyze similar antenna reflectors in the future.
