| 摘 要： | 研究了飞机结构弹性对起落架缓冲性能的影响。建立了计及飞机结构弹性效应的起落架缓冲系统的动力模型和分析方法。应用结果表明，飞机结构弹性效应能降低起落架缓冲系统的过载、位移等，尤其对大、中型飞机主起落架更为明显，如，某Ｙ机主起落架过载降低６％。

| Abstract: | The effect of aircraft structure flexibility on the shock-absorber behavior of landing gears is discussed.The dynamic model and ahalyticl method of the shock strut system can cerning the effect of flexible aircraft are established. Applications hvae shown that the aircraft structure flexibility can decrease the overloat and displacement of the shock strut system, especially,for the main landing gears of large and middle size airplanes.Therefore,considering the aircraft strcture flexibility can not only predict the ground loads of aircraft correctly,but also is of important value to the parameter design of landing gears. |
