Abstract: 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.
