摘要
为提高某型无人机伞降回收系统的可靠性,采用硬件法与功能法相结合的方法对该系统进行了故障模式及影响分析,利用定量分析方法和危害性矩阵图对该系统的危害性进行了分析。研究结果表明,需要对"主伞故障"这一失效模式加以重点关注。给出了使用中应采取的预防措施,使系统的可靠性得到了显著增长。
In order to improve the reliability of UAV parachuted recovery system, combined with the hardware and the function, the fault mode and effects was analyzed. By use of quantitative analysis and criticality matrix, the fault criticality was analyzed. It was concluded that the fault mode of parachute inaccurate furl should be focused on; the preventive measures was given, which significantly improves the system＇ s reliability.
