全机落震动力学环境研究

Research on the Dynamic Environment of Full-Scale Aircraft Drop

本文利用MSC.ADMAS软件构建了起落架、刚柔耦合全机动力学模型,对飞机全机落震整个过程进行动力学仿真,分别得到了前起落架、主起落架的特征变化曲线,以及全机落震过程中飞机重心处X、Y、Z三个方向的过载。

With the landing gear and rigid-flexible coupling full-scale aircraft dynamic model constructed via MSC.ADMAS software.A dynamics simulation to the whole process of full-scale aircraft drop is conducted in this paper to obtain the characteristics changing curves of the nose landing gear and main landing gears,as well as the G-load in X,Y and Z directions at the gravity center of the aircraft during the process of full-scale aircraft drop.
