Currently,the research on the low frequency vibration coupled with brake problem of landing gear is focused on longitudinal single-degree-of-freedom coupling vibration.By establishing the multi-body dynamics model of multi-degree-of-freedom low-frequency brake-induced coupling vibration of the two-wheel telescopic landing gear,and stimulating the six-degree-of-freedom bushing model at the connection between the fuselage and the main landing gear to simulate the longitudinal,lateral and torsional stiffness and damping of the landing gear pillar,the multi-degree-of-freedom coupling vibration characteristics of the landing gear are analyzed in detail.The results show that the pillar stiffness and braking torque amplitude are of great influence on the amplitude,acceleration and load of coupled vibration under the condition of low frequency braking.The coupling vibration on the landing gear can be suppressed by increasing the structural stiffness,damping and braking torque frequency or reducing the braking torque amplitude.Under the condition of asymmetric brake of the left and right wheels of the landing gear,lateral and torsional coupling vibration of the landing gear occurs,and the coupling vibration is intensified with the extended gap between the frequency and amplitude of the asymmetric braking torque of the left and right wheels.
