摘　　要：飞机防滑刹车系统是一个重要的机载设备,当跑道有冰、雪时,飞机不但不易刹停,还难以保持两侧平衡;文中对飞机防滑刹车系统的工作原理进行了分析,针对飞机在非均匀结合系数跑道上容易侧滑这一现象,提出了双通道平衡调节控制方法;在计算机建立的飞机模型基础上,将刹车控制单元接入仿真回路,形成了飞机刹车半实物仿真系统,可以实现飞机在各类环境下的刹车模拟实验;仿真结果表明,提出的双通道平衡控制方法响应迅速,有效抑制了机体侧滑,保障了刹车系统的安全,为刹车系统的设计与改进提供了试验依据。Aircraft Anti-skid braking system is an important airborne equipment,when the runway covers with ice and snow,the aircraft is not only hard to brake,but also difficult to maintain a balance on both sides.In this paper,the working principle of aircraft anti-skid braking system is analyzed,and proposed a dual-channel balance adjustment control method in reaction to the phenomenon that the aircraft is easy to sideslip on the runway with non-uniform coefficients.Based on the aircraft model in the computer,the brake control unit is connected to the simulation circuit to form a semi-physical simulation system,and the aircraft can be achieved many braking simulation experiments in various environments.The simulation results indicate that the proposed dual-channel balance control method responds quickly,prevents aircraft sideslip effectively,protects the safety of the braking system,and provides a test basis for designing and improving the braking system.
