摘要
基于Adams/Aircraft软件建立了某飞机虚拟样机,和基于Matlab/Simulink软件建立的前轮转向、推力和防滑刹车系统实现联合仿真,模拟了飞机的地面匀速转弯和刹车操纵运动,得到了飞机的动响应。研究表明:飞机转弯过程中载荷峰值出现在初始非稳态时刻;滑移率控制式防滑刹车系统使飞机在整个刹车过程中保持最佳刹车性能。
The virtual prototyping of an aircraft is built in the Adams/Aircraft software. The co-simulation of the nose wheel steer system, thrust system and anti-skid braking system is established based on Matlab/Simulink software. The aircraft ground handling movement is simulated, and the dynamic response process and load distributions are obtained by co-simulation of Matlab/Simulink and Adams/Aircraft. The research indicates that the top loads of the aircraft appear at initial unstable time while steering; The slip-ratio controlled anti-skid braking system can obtain best performance during the whole braking course.
