【摘要】：近年来,中国航天产业得到了迅猛发展。由于航天产业具有高风险性,因此,航天产品的安全性高低代表了航天产业与航天型号发展水平的高低。为了提高航天产品的安全可靠性,近年来,中国航天可靠性工程技术逐渐被人们了解、肯定与使用。本文对航天型号的可靠性管理、分析进行了探讨,并开发了航天型号可靠性分析软件。首先,根据国内航天型号研发的实际情况,制定了符合我国航天型号标准的可靠性管理程序。并对程序中各个环节的主要可靠性技术基于航天型号的作用与运行标准进行了详细阐述。其次,描述了航天型号可靠性管理中常用的故障树分析法,逐一介绍了故障树分析的主要环节与实现程序。并通过研究XX发射平台摆杆系统射前无法摆开的故障树,展示了在故障树分析法基础之上的航天型号可靠性分析方法。第三,针对航天机器可能存在的问题展开了故障模式影响与危害分析研究,包括故障模式分析、故障影响和原因分析等内容。并探讨了当前航天机器中开展故障模式影响及危害分析研究时常遇到的情况以及解决对策。最后,围绕本论文提出的航天型号可靠性管理体系,开发了航天型号可靠性分析软件平台,并对此平台的构造、重要模块以及代码实现进行了介绍。
[Abstract]:In recent years, China's space industry has been developing rapidly. Because of the high risk of space industry, the safety of space products represents the development level of space industry and space model. In order to improve the safety and reliability of space products, in recent years, China's aerospace reliability engineering technology has been gradually understood, affirmed and used. In this paper, the reliability management and analysis of the space model are discussed, and the software for the reliability analysis of the space model is developed. First, according to the actual situation of the domestic aerospace model and development, the reliability management program is formulated in accordance with the standard of China's space model. And the main reliability technology of each link in the program is based on the function and operation standard of the space model. Secondly, the fault tree analysis method commonly used in the space model reliability management is described, and the main links and the implementation procedures of the fault tree analysis are introduced one by one. The fault tree and by studying the XX pendulum system launch platform before launch cannot be laid out, demonstrated in fault tree analysis of aerospace reliability based analysis method. Third, aiming at the problems that may exist in the space machine, the failure mode influence and hazard analysis research is carried out, including failure mode analysis, fault influence and cause analysis. At the same time, it also discusses the current situation and Countermeasures of the failure mode influence and hazard analysis research in the space machine. Finally, around the reliability management system of aerospace type proposed by this paper, we developed the software platform for reliability analysis of aerospace models, and introduced the construction, important modules and code implementation of this platform.
