Abstract
|
Aircraft landing gear system is an important airborne device of aircraft, which plays an important role in taking off and safe landing . However,its design includes many contents ,covers a wide rang of subjects and is a complicated process, so the hardware -in - loop simulation is utilized to in analysis and study of landing gear system research.First, the dynamic characteristics insufficiency of landing gear fails to be considered into braking system simulation research, the paper narrates the performance of the landing gear in the process of anti-skid braking and the landing gear’s dynamic character., and made an in-depth study into the influence of breaks in asymmetry and the influence of the transmogrification of landing gear member under brake on set of brakes.Secondly, Aim at the technical specifications of hardware-in-loop-simulation project of aviation wheel set of braking systems, through studying the system , it is proposed of the hardware-in-loop simulation braking system of basing parallel computer system. The paper depicts the overall design frame of the hardware-in-loop simulation, introduces the constituent element of the system, the connection of practicality and simulation platform, and the design of software.The hardware-in-loop simulation design have accomplished,and passed closed loop debugging. the result shows that the mathematical model is basicly logical and Vague control is feasible.furthermore, the hardware -in-loop simulation can simulate the dynamic behavior of set of brakes of aircraft comparatively veritably.This system basicly achieves user requirement, and provides a good testing platform for optimal design of brakes of future aircraft.
