飞机防滑刹车系统动态特性仿真研究

以国内某现役机种为对象,本文在综合考虑了飞机机体、起落架、轮胎、传感器等特性的基础上,推导了适用于飞机刹车滑跑的动力学模型,该模型重点考虑了起落架和轮胎的动态特性,突出简单、实用和通用性的要求,并加入到相对滑动量控制的电子防滑刹车系统的数字仿真软件中,完善了防滑刹车系统的软件平台,以用来研究飞机系统的动态特性与刹车性能的关系.利用本软件对飞机刹车动态性能作了全面的定量分析,对设计和改进刹车系统有重要的指导意义. 

Dynamic Characteristics Simulation of Aircraft Anti-Skid Braking System

Based on the dynamic response of aircraft body, the spring, damping of landing gears, friction characteristics of the tires,sensors, and so on,mechanical model for aircraft anti skid braking system is set up.The model is simple but practical and universal,which is integrated with velocity rate controlled and pressure bias modulated aircraft anti skid system.Simulation software for braking design is developed and revised. By using the software and taking some fighter in China as an example,this paper discusses relation between the aircraft dynamic response and braking performance,especially the influence of landing gears and tires on braking performance.Some valuable conclusions, which are helpful to design and improve the aircraft anti skid braking system,are drawn.
