航天用元器件应用验证方法及其应用实例

针对航天用元器件传统鉴定考核方法的局限性，文章提出了一种改进的可靠性保证方法，其核心在于以元器件鉴定试验为基础，结合航天应用的实际背景以及元器件的自身特性制定评估试验方案，对元器件的耐受力裕度、实际性能指标进行评价。将该方法应用于航天器用1553B数据总线隔离变压器的评估，得出了在不同应用条件下其电性能参数的变化趋势以及与进口同类样品间电参数的比对结果，并对其结构与航天型号要求的符合性以及极限性能指标等进行了评估验证。结果表明，该方法可以充分验证航天用元器件研制的成熟度和在航天工程中的适用度，为元器件的研制和应用提供全面参考依据。

Application validation method for space components

An application validation method for space components,as an enhanced reliability insurance approach,is proposed to verify the maturity and the adaptability of the components.It is based on the conventional qualification test of components,while taking account of the component’s application background and its characteristics,to form an assessment scheme to evaluate the component’s tolerance margin and actual performance.This method is implemented to evaluate the space-level 1553B data bus isolation transformer.The variations of its electrical parameters in different application conditions are obtained,with a comparison between the domestic-made and the imported similar products.Verification is also made whether its structure satisfies the aerospace requirements and the requirements for its limit performance.It is shown that this method is practical and can provide a comprehensive reference basis for the development of space components.
