So far the magneto-rheological(MR) effect mechanism of MR damper has not been known completely, especially in the impact load,and the problem becomes more complicated and difficult for analyzing.A set of characteristic tests and parameters’ identification are made to the MR damper by the experimental platform. The dynamical model of the damper is constructed based on the Bingham plastic model,and the buffer control strategy of aircraft undercarriage based on MR technology is established.Finally,the fuzzy control algorithm is applied to the process of automatic control for landing buffer of aircraft undercarriage.The simulation results show that the proposed MR damper pulley buffer can effectively recognize the impact energy.The research has a better application in the engineering.
So far the magneto-rheological (MR) effect mechanism of MR damper has not been completely over, especially in the impact load, and the problem becomes more complicated and difficult for analyzing. A set of characteristic tests and parameters’ identification are made to the The damper model of the damper is constructed on the Bingham plastic model, and the buffer control strategy of aircraft undercarriage based on MR technology is established. Locally, the fuzzy control algorithm is applied to the process of automatic control for landing buffer of aircraft undercarriage. The simulation results show that the proposed MR damper pulley buffer can effectively recognize the impact energy. The research has a better application in the engineering.
