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。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。结果表明:由飞参数据提取的载荷状态信息,相较于规范载荷工况更接近于实际损伤模式。
The landing gear is a key part of the aircraft during take off and landing.The strength of its structure directly affects the safety in the take-off and landing process.The landing gear of the aircraft is designed in accordance with the strength and rigidity specification.The attitude and motion information during landing process from flight data of a certain aircraft are extracted to analyze the ground loads of the landing gear.The results show that the analysis based on flight date is more accurate than on the specification and three-dimensional load may be one of the causes for the damage of landing gear.
