摘要
管接头等密封结构是作动筒可靠工作的重要组成部分,为保证作动筒的功能使用要求,结合某型飞机主起落架收放作动筒管接头结构特点,从结构功能、连接强度方面对管接头进行分析,对管接头结构尺寸精度及保险销直径进行优化改进,结果表明:改进后的管接头结构能满足预期使用要求。
The sealing structure such as pipe nipple is an important part of the actuating cylinder for reliable work.In order to ensure the functional use requirements of the actuating cylinder,in this article,the pipe nipple is analyzed based on the structural characteristics of the pipe nipple which is located in the main landing gear actuating cylinder of an aircraft.Combined with structural function and connection strength analysis,the structural dimension accuracy and pin diameter of the joint are optimized.Results show that the improved pipe nipple structure can meet the the expected requirement.
