Simulation Research On Aircraft Arresting System

When aircraft lands on a harsher condition by the guidance of automatic landing system, it needs a auxiliary devices if it wants to retard brake and land safely. And the landing speed is fast and time is short. Aircraft arresting system is an energy conversion device, which converts large kinetic energy into other energy forms.American BAK-12 aircraft arresting device is taken as reference foundation in this paper. The aircraft arresting device's major components are two energy converters with identical structure which symmetrical arranged on the both sides of the flight runway. The mechanical structure of the energy converter is composed of several big functional modules: the rope pulley organization, the transmission system, the cam gear, and it also contains some auxiliary mechanisms and devices.On the basis of some correlated data, a rope model is established in the ADAMS software environment, and the arresting system model besides of arresting rope set up in the AMESIM environment Through co-simulation between AMESIM and ADAMS, the model analyzes the impact of the aircraft arresting that caused by the tension waves of the rope, and the circumstance of the aircraft bias to runway center.Through analyzing of BAK-12 aircraft arresting principle, and then taking the primitive design variable as the foundation, a more realistic simulation model of arresting is established in AMESIM. The relationship between system output pressure and the aircraft stop time during the arresting process is analyzed under the condition of aircraft with different mass and speed. To specific aircraft, fuzzy control is carried out to revise the exceeded pressure so as to satisfy the requirement of the arresting.
