摘　　要：以某型飞机主起落架机轮半轴的疲劳断裂事故为研究背景,利用有限元法对某型飞机机轮半轴进行了静态受力分析,得到了飞机机轮半轴的断裂部位与受力特点,同时进行了机轮半轴动态特性分析,并给出了部分固有频率和振型。所得计算结果为研究和改进某型飞机机轮半轴设计提供了依据。On the background of accidents caused by the fatigue fracture of main landing wheel axle,an analysis on the static forces of the wheel axle in an aircrafts by the finite element method.The fracture sites and failure forms were got.At the same time,dynamic characteristics analysis to the wheel axle is also made,and parts of natural frequencies and modes were obtained.The results could be applies as a reference to further research and design to the wheel axle of a aircraft.
