摘　　要：飞机着陆时与地面撞击将产生较大的撞击能量,大部分能量需要通过起落架缓冲器吸收,在进行飞机设计时首先要对能量吸收过程进行计算分析,也就是通常所说的缓冲性能分析。本文将对各种起落架,包括单气腔、双气腔、双油式起落架缓冲器进行数学建模,为缓冲性能分析及未来的试验仿真打下基础。It will bring much impact energy when aircraft lands on the earth. Because most of the energy is absorbed by the buffer on the langing gear, we have to analyse the process of the energy absorption during the aircraft design which is called; Buffurring Function Analysis. The paper builds the mathematical models of buffer, such as single air cavity, double air cavity. Also it will give basis to the Buffer Function Analysis and the testing simulation.
