可靠性评估方法在运载火箭阀门中的应用

摘要

In this paper, the particularity of spaceflight mechanical product by relief valve sample was analyzed.According to the reliability target and assignment, a model of reliability evaluation is present and examination system is built. The result shows that reliability evaluation method of safety-relief valve is efficient and exactitude.%首先论述了阀门可靠性评估的国内外研究现状,然后以减压器为例分析了航天阀门的工作特点,结合其任务剖面,并根据增压输送系统分配的可靠性指标,建立了适于工程应用的可靠性评估模型.
