某无人机着陆滑跑动态仿真分析

Dynamic Simulation of Landing and Rolling for a Certain UAV

用Catia建立全机模型,然后导入到Adams/View板块中进行仿真,首先对起落架进行落震仿真,以确定起落架缓冲弹簧的参数,保证起落架的着陆安全。然后再进行全机着陆、滑跑仿真,确定飞机的刹车力的施加时间以及跑道的长度,为以后飞机的真实着陆、滑跑提供安全依据。

In this article, Catia is used to establish the whole airplane model, and then import it into Adams / View section. Drop-simulation is done on the landing gear which is used to determine the parameters of the spring. In this way, we can ensure the safety of the landing gear. And then full- landing and roll simulation will be carrying on which is used to determine when to impose the force on landing gear and the length of the runway. All of above provide a safe basis for the real landing and rolling.
