| Abstract: | Based on the rupture accident of main landing gear axle used in the airforce,the article analyses the phenomenon on the fracture failure of main landing gear axle,and checks up the material of the main undercarriage structural member,measures the correlative size and the parameter of the oleo-pneumatic shock absorber to find causation of the axle's fatigue fracture.It establishments a few measure to prevent such accident from taking place again. |
| Keywords: | landing gear axle fracture stress concentration low-cycle fatigue |
