某型号起落架缓冲性能故障分析和改进措施

Buffer Capacity Failure Analysis and Improvement Measures for L/Gs of a Certain Type of Aircraft

起落架是飞机的重要部件之一,其重要功能是减少飞机在起飞和着陆过程中地面对机体的冲击,保护机体结构免受损伤。本文详述了某型飞机起落架落震试验中出现的问题,并通过对试验数据和缓冲器结构的分析,找到了产生故障的原因,提出了改进措施,可为今后解决类似问题提供参考。

The landing gears(L/Gs) are the critical components of aircraft,its critical function is to decrease the impact load to the wheels from the ground,which transfers to the aircraft structure during aircraft take-off and landing so as to protect the airframe structure from being damaged.This paper expounds the problem appearing in the drop test of L/Gs for a certain type of aircraft and whole process of finding out the cause and troubleshooting by means of analysis on the test data and buffer construction for the benefit of reference to the solution to the similar problem for the future.
