A new method called multi-disciplinary collaborative simulation was presented for research of aircraft ground maneuver characteristics.The virtual prototype established in ADAMS/Aircraft which was taken as core and was validated by the results of drop and static loads tests, integrated with the aircraft and landing gear geometry components built in CATIA.The flex parts exported from PATRAN/NASTRAN, and the control system established in MATLAB,were used to implement the multi-disciplinary collaborative simulation of aircraft ground maneuvers, such as, ground steering, anti-skid braking,and shimmy.The results show that: this method can model aircraft ground maneuvers accurately,and some useful conclusions are obtained. 

将多学科协同仿真技术应用于飞机地面动力学研究,以ADAMS/Aircraft软件的多体动力学建模为核心,联合CATIA软件生成飞机和起落架几何构件,联合PATRAN/NASTRAN软件进行模态分析生成柔性体,联合MATLAB软件建立控制系统模型,采用落震与静力试验的结果校核模型,然后对飞机地面滑跑转弯、防滑刹车、摆振等运动进行多学科协同仿真。结果表明,该仿真模型能准确模拟飞机的地面运动,并得到一些有意义的结论。
