| 摘 要： | 起落架是飞机起飞和着陆过程中的关键部件，其结构强度的优劣直接影响着飞机的起飞和着陆安全。本文针对某飞机依据强度和刚度规范设计出的起落架在某次着陆阶段出现的损伤故障，利用飞机的飞参数据，从中提取飞机着陆时的姿态与运动信息，分析飞机起落架的地面载荷信息，从而为故障排查提供参考和输入。分析结果表明，在某些情况会出现的三向载荷复合作用是导致该起落架结构损伤的可能原因之一。

| Abstract: | The landing gear is an important part of the aircraft. The strength of its structure directly affects the safety in the take-off and landing process. The landing gear of the aircraft is designed for the strength and rigidity specification. This paper extracts the attitude and motion information during landing process from flight data to analysis ground loads of the landing gear, thus providing reference and input for troubleshooting. The results show three-direction load may be one of the causesfor the damage of landing gear. |

| Keywords: | Structural strength ground load landing gear flight data |
