摘要
提出了可靠性特征量裕度的概率设计方法,建立了可靠性指标、裕度系数和特征量设计值之间的定量关系,分别论述了航天器的机构传动裕度、密封件密封裕度、防热结构防热裕度、火工连接解锁装置装药裕度的概率设计方法,为航天器机械产品可靠性量化设计提供了技术途径。
Quantitative relations among reliability requirments, margin coefficients and designed values of characteristic parameters were established. Probability design methods of MOS for mechanism transmissions, structure seals, structure thermal protections and pyrotechnic connecting/unlocking devices were respectively discussed. The work offers a technical approach for quantitative reliability design of space mechanical products.
