摘　　要：雷击直接威胁飞行安全,为了进一步确定飞机的雷击特性,依据SAE-ARP5416和国内相关标准的规定,利用基于有限元法的数值仿真技术对飞机雷击附着点和雷击附着区域的划分展开研究。以空客A320飞机为例,按照飞行过程中可能遭受的雷击情况,对其进行了等比例模型下的建模仿真。提出了一种新的飞机雷击附着区域划分的数值仿真方法,研究了数值仿真模型建立的相关问题,并对飞机雷击附着区域中的1A区域进行划分,并将数值仿真结果与SAE-ARP5414A标准结果进行了比较。提出的方法对飞机的防雷设计和相关研究有重要的参考价值。The lightning is a threat to the safety of flying aircraft. In order to further determine the characteristics of lightning stroke to aircraft, according to SAEARP5416 ＂Aircraft Lightning Test Methods＂ and relevant standards of our country, simulation methods based on finite element are used to simulate lightning attachment points and lightning zoning on the Airbus A320. A new simulation method of aircraft zoning is proposed. Relevant content about simulation model is discussed. The division of 1A zone of the lightning zoning is present and the numerical results are compared with SAE-ARP5414A standard. The presented method and numerical results are of great value to lightning protection Of aircraft and related studies.
