| 摘 要： | 基于牛顿-欧拉多体动力学建模方法,建立了三体九自由度飞机对称着陆动力学模型.以某型双腔缓冲器起落架飞机为例,通过飞行实测不同状态下的起落架着陆动态载荷,仿真计算相应的着陆重量、着陆下沉速度及着陆姿态下的着陆动态载荷.验证分析结果表明,所建飞机对称着陆多体动力模型是有效的.

| Abstract: | A symmetry landing dynamics model with 3 bodies and 9 dimensions for aircraft was established based on Newton-Euler mulit-body dynamics modeling method.The model was verified by flight test taking a certain type of aircraft as an example,the landing gears of which are dual-chamber shock absorbers.The simulation and the measured results are both given with varieties of landing weight,sink speed and pitch angle.It is shown that the model is effective for aircraft symmetry landing by comparing the two results. |
