摘要
飞机刹车系统性能直接影响飞机起降安全,尤其对使用差动刹车实现地面方向控制的飞机,刹车系统响应慢会导致纠偏失效、飞机冲出跑道等事故。以中小型飞机刹车系统为研究对象,介绍先进电传刹车系统组成及工作原理,建立电静液刹车系统模型,对刹车系统的满量程响应及10%阶跃响应进行动态仿真研究。仿真结果表明:刹车压力响应满足设计要求。将仿真结果与试验数据进行对比分析,验证了仿真结果的正确性。该研究为刹车系统控制律设计提供参考。
The performance of the aircraft braking system directly affects the safety of the aircraft taking off and landing,especially for the aircraft using differential brake to realize the ground direction control,the slow response of the brake system will lead to the failure of rectifying deviation,resulting in the aircraft over running the runway and other accidents.Taking the small and medium sized aircraft braking system as the research object,the composition and working principle of the advanced electro-hydraulic braking system were introduced,the electro-hydrostatic braking system model was established,and the dynamic simulation study on the full range response and 10%step response of the braking system were carried out.The simulation results show that the brake pressure response meets the design requirements.The simulation results were compared with the experimental data to verify the correctness of the simulation results.The study provides reference for the design of the brake control law.
