| 摘 要： | 主要建立了全机和支柱式起落架缓冲支柱的数值模型，并进行了着陆和滑跑仿真计算。建模主要考虑了缓冲支柱的初始压力、初始容积、油孔面积、活塞面积、缓冲支柱行程等参数。同时给出了飞机在对称着陆和滑跑时的运动学公式，推导了缓冲支柱和轮胎垂直力的计算公式。建立了数值模型并进行着陆和不同跑道的滑跑仿真计算，这对飞机设计和指导起落架试验具有一定工程实用价值。

| Abstract: | The main job was to establish the model of full aircraft and landing gears and run a symmetric landing and taxiing simulation. The analysis and design calculation of the pillar landing gear＇s shock absorber performance was introduced. Some main parameters, such as ：air volume at static extension,orifice area,and total stroke etc, were designed. The kinematics and dynamics equations for landing and taxiing was introduced mean while, then ran a simulation for symmetric landing and taxiing of full aircraft. The results of aircraft＇ s landing gear may be useful for engineering applications. |
