Abstract: Anti-skid braking systems are often coupled with the landing gear structure during aircraft braking, which negatively impacts the gear's durability and safety. In this study, the longitudinal vibration generated by the coupling of multi-wheel landing gear and anti-skid brake systems is examined. First, a hybrid dynamic model of the landing gear is built using LMS Virtual.Lab and Abaqus. Next, a brake system model is created in Matlab/Simulink, and the interface is added to establish the co-simulation model. The modal analysis of the landing gear structure is then performed based on this model, and the transfer function between the gear's walking vibration response and brake pressure is analyzed.
