Abstract

In this paper, a two-degree of nonlinear vibrating system of landing gear is studied. A delayed velocity feedback is applied to suppress the vibration of the landing gear structure. The dynamical behavior of landing gear system is investigated when the 1:3 internal resonance and primary external resonance occur simultaneously. Two cases of primary resonance are analyzed when the external frequency nears to the first and second mode frequency of the system. The effects of delayed feedback gain and time delay on the vibration of the landing gear system are investigated. The results show that the suppression ability is improved when the value of delayed feedback gain is increased. However, the unstable range of the system is enlarged with the value of delayed feedback gain increases. Another result is that the amplitude of the landing gear system can be suppressed to a minimum value if the time delay is chosen properly.
