| 摘 要： | 简述了系统安全性分析与设计的发展现状,指出了其4个重要组成部分的内在逻辑关系;阐述了系统安全性设计的定性分析方法,提出了新的功能危害性分析(FHA)、故障模式和影响分析(FMEA)中对二次故障、多重故障及隐蔽故障的处理方法;建立了用于底事件定量分析的秩统计法,利用不完全寿命数据平均秩,导出了不完全寿命分布参数估计公式;建立了一整套更为合理、更为精确的系统安全性设计与分析技术.该技术已成功应用某机型襟翼操纵系统安全性设计与分析.

| Abstract: | Based on the logical relations among its four major contents and a qualitative approach of system safety analysis and design, a new method for the treatment of a secondary failure, multiple failure and hidden failure in FHA and FMEA were proposed. Moreover, a mean rank method for the quantitative analysis of the base events was given by which the distribution parameter estimation formulas of the incomplete life data were derived. Finally, a more appropriate and accurate technological package for system safety analysis and design was established and applied to the system safety engineering of some airplane flaps successfully. |
