基于故障危害度对飞机电源系统进行可靠性评估,首先建立可靠性评估模型,该模型考虑各故障样本对飞机电源系统供电可靠性危害度影响,将出现的故障按照对电源系统安全、性能、任务及维修等指标的影响程度进行等级分类,从故障的失效机理出发建立相应的分布模型;然后采用分布计算和二次分布等算法进行系统整体可靠性指标评估。应用该模型对飞机电源系统进行了故障统计分析,计算了飞机电源系统的可靠性指标。
Based on the degree of fault hazard, the reliability evaluation of the aircraft power system is first established. The reliability assessment model is first established. The model takes into account the impact of each fault sample on the reliability of the aircraft power supply system reliability. The fault according to the power system safety, performance, Maintenance and other indicators of the level of impact classification, starting from the fault failure mechanism to establish the corresponding distribution model; and then using distributed computing and quadratic distribution algorithm for the overall system reliability index assessment. The model is applied to the fault analysis of the aircraft power system and the reliability index of the aircraft power system is calculated.
