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。The mathematical model of landing dynamics was presented. Based on analysis of aluminum honeycomb characteristics, an M-honeycomb shock absorber modal 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.
