Semi-physical Simulation of Multi-wheel Aircraft Braking System Based on Virtual Prototyping

Anti-skid Braking Control Box is one of the most important equipments in the aircraft. It is dangerous and costly to modify the parameters of the controller directly. In the paper, a digital aircraft is built, and the velocity-rate-controlled and pressure-bias-modulated control algorithm with balance compensation is used in the Anti-skid Braking Control Box, USB input/output Board exchanges data between the digital aircraft and Anti-skid Braking Control Box. Digital aircraft can show many analyses quickly on the computer by figure and their fidelity is so high that many parameters can be modified easily, the sideslip is restrained effectively, and the braking efficiency is high.
