在笛卡尔坐标系中建立了飞机起落架着陆过程的等效数学模型;基于ADAMS/Aircraft模块建立了多轮式起落架的着陆动态性能分析模型并完成全机数字样机的装配。对仿真结果进行研究分析,得出结论:多轮式起落架能够有效地分散地面载荷,大大地减小起落架单个机轮承受的压力,增大飞机的漂浮性,提高飞机起飞着陆的安全性,并在一定程度上延长起落架及跑道的使用寿命。该研究内容及方法为今后的大飞机起落架设计提供有益的参考。
In the Cartesian coordinate system, an equivalent mathematic model of the landing process of the aircraft landing gear is established. Based on the ADAMS / Aircraft module, the landing dynamic performance analysis model of the multi-wheeled landing gear is established and the assembly of the full digital prototype is completed. The simulation results are analyzed and concluded that the multi-wheeled landing gear can effectively disperse the ground load, greatly reducing the pressure on a single wheel of the landing gear, increasing the buoyancy of the aircraft and improving the safety of take-off and landing of the aircraft , And to some extend the service life of landing gear and runway. The contents and methods of this study provide useful references for the design of large landing gear in the future.
