【摘要】：对于飞机雷击的风险,运用事故树模型的分析方法,建立飞机雷击事件事故树模型,综合考虑飞机雷击事件发生的全过程。通过建立飞机雷击事件事故树模型,阐述引起飞机雷击的主要原因,同时得到最小割集、最小径集,运用公式计算出基本事件的结构重要度。当飞机雷击事件发生后,根据组成最小割集的基本事件,找出造成飞机雷击事件发生的根本原因,运用最小割集方法来制定预防飞机雷击事件发生的方案。同理,根据最小径集中基本事件都不发生时雷击事件不会发生来制定预防飞机雷击事件发生的方案。根据结构重要度的排序,找出预防飞机雷击事件发生的关键途径,提出了预防的方案,方案可以作为相关工作人员的工作手册或者检查单。飞机雷击事件树模型系统直观地展示了引起飞机雷击事件发生的各基本事件的逻辑关系,为降低飞机雷击事件的发生提供了高效的方法。
[Abstract]:For the risk of aircraft lightning strike, the accident tree model is used to establish the accident tree model of aircraft lightning strike event, and the whole process of aircraft lightning incident is taken into consideration. By setting up the accident tree model of the aircraft lightning strike event, the main causes of the aircraft lightning strike are expounded, and the minimum cut set, the smallest path set are obtained at the same time, and the formula is calculated. The structural importance of the basic event. After the incident of the aircraft lightning strike, the basic cause of the occurrence of the lightning strikes is found out according to the basic events of the minimum cut set, and the scheme of the minimum cut set method is used to prevent the occurrence of lightning strikes. According to the order of the structural importance, the key ways to prevent the lightning strikes are found, and the prevention scheme is put forward. The scheme can be used as the work manual or checklist of the related staff. The aircraft lightning event tree model system shows the aircraft thunder directly. The logical relationship between the basic events that hit the incident will provide an efficient way to reduce the occurrence of the lightning stroke.
