中文摘要:
为了提高和评价激光火工系统可靠性，本文采用GO法建立了激光点火系统可靠性模型，并进行可靠性定性分析和定量计算.首先，通过元器件应力法预计激光点火系统各个组成模块的可靠性参数，然后通过GO法定性分析得到该激光点火系统的最小割集，并采用GO法定量分析计算系统非工作状态贮存5 y、工作状态工作时间1 h任务剖面下系统作用可靠度.通过与故障树定性分析结果、蒙特卡洛仿真分析结果对比，验证了采用GO法对激光点火系统进行可靠性分析的正确性与合理性.
English Summary:
To enhance and evaluate the reliability of laser ignition systems,reliability model of laser ignition system was established by using GO methodology. The results of reliability analysis including minimal cutset of the system gotten by using GO methodology qualitative analysis and reliability of laser ignition system calculated by GO methodology quantitative method were carried on. Reliability parameters of various modules were predicted by using component stress method under the mission profile of non-working state for 5 y and working state with working time of 1 h. Compared with the results of FTA and Monte Carlo simulation,the applicability and the accuracy of reliability analysis of laser ignition system based on GO methodology are verified.
