Simulation Modeling and Analysis of Landing Gear Brake-Induced Buffeting

This paper establishes a joint simulation model for landing gear vibration problems. Based on the model, the influence laws of different braking control methods, different runway conditions, and different positions of the rear strut on the main landing gear vibration are compared and analyzed. The results show that the runway conditions have a certain influence on the landing gear braking performance and heading vibration; the rear strut landing gear has better vibration response, and the vibration displacement is reduced by 10–20% in all simulation conditions compared with the strut in front.
