| 摘 要： | 给出了着陆动力学分析的数学模型，并在分析铝蜂窝材料缓冲特性的基础上，建立了 铝蜂窝缓冲器模型，将其应用于软着陆机构单条着陆腿冲击仿真。仿真结果表明，该模型在 缓冲行程、能量吸收及缓冲后加速度响应峰值等方面与试验结果基本一致。为软着陆机构着 陆冲击动力学分析时铝蜂窝建模提供参考。

| Abstract: | The mathematical model of landing dynamics was presented.Based on analysis of aluminum honeycomb characteristics,an Al-honeycomb shock absorber model was derived.The model was utilized in one-leg impacting simulation of the landing gear.Analysis results show nice agreement with test data in these aspects: stroke displacement,energy absorption,acceleration response and its peak value.It is referable to modeling of shock absorber with Al-honeycomb for investigation on landing dynamics of landing gear system. |
