基于Amesim仿真软件的飞机起落架油气式缓冲器动态性能研究

Research on the Dynamic Performance of Aircraft Landing Gear Hydro-pneumatic Buffer Based on Amesim

针对油气式缓冲器Amesim仿真软件建模应用技术研究不足的问题,以单腔和双腔飞机起落架油气式缓冲器为对象,开展了利用Amesim仿真软件对缓冲器的仿真建模研究。在分析单腔和双腔油气式缓冲器工作原理的基础上,建立了Amesim仿真模型,并进行了落震仿真试验。仿真试验的结果对指导飞机缓冲器的结构设计具有较大的参考价值。

Aiming at the problem of insufficient research on the modeling application technology of the Amesim simulation software for the hydro-pneumatic buffer,this paper takes the single-cavity and double-cavity aircraft landing gear hydro-pneumatic buffer as the object,and carries out the simulation modeling research on the buffer using the Amesim simulation software.Based on the analysis of the working principle of single cavity and double cavity hydro-pneumatic buffer,the Amesim simulation model is established and the falling shock simulation test is carried out.The results of simulation test are of great reference value to the structural design of aircraft buffer.
