摘　　要：分析了当前国内外主流商业可靠性软件工作模块完备性不足、模块"组合化"的特点与航天器全研制周期可靠性工作数字化、信息深度关联融合实际需求的差距,设计了航天器研制一体化可靠性系统。该系统架构为产品设计工作和可靠性工作提供同一工作平台,以统一数据库为基础,深度集成不同厂家的可靠性软件,满足航天器全研制周期的可靠性数字化工作需求;对产品技术状态管理、可靠性大纲与策划、可靠性报告编制等目前需要人工工作的部分进行数字化设计;基于统一数据库,深度融合可靠性建模、故障模式与影响分析(FMEA)、故障树分析(FTA)、潜通路分析等多种可靠性软件。在探月三期工程轨道器研制中的应用实践表明:一体化可靠性系统契合航天器研制特点,能够实现全研制周期的可靠性工作数字化,提高了轨道器可靠性工作的全面性、灵活性和方便性,具有很高的工作效率。The general commercial reliability software is lack of completeness and is module simple combination,but the whole period of spacecraft development needs to be digitized,and the information needs deep correlation fusion.An integrated reliability system which can satisfy the whole development cycle of spacecraft is designed,and the system provides the same platform for product design and reliability work,integrating of reliability analysis software from different manufacturers,and establishing a common database.Manual work of product technical condition management,reliability planning,report compilation and so on is digitized.Based on unified database,multiple reliability software is deeply integrated such as reliability modeling,FMEA,FTA,LPA and so on.The orbiter development practice of the third phase of Lunar Exploration Project shows that the system can meet the characteristics of spacecraft development and the reliability work of the whole development cycle can be realized with digital tools.The reliability work of the orbiter development process is very comprehensive,flexible and convenient and has a high efficiency.
