Abstract: Aiming at the restricted application range of magnetorheological damper (MRD)with external power supply, based on the working characteristics of MRD and the investigation about harvesting energy from the vibration,a new type of Energyregenerative MRD (called selfpowered MRD) was proposed. According to the analysis on function modules of Energyregenerative MRD, the design methods of MRD integrated Energyregenerative device was investigated to confirm their structure parameters, the electrical circuit was designed in accordance with Energyregenerative device .Particularly,at the vibration condition of 1Hz to 3Hz frequencies and 10mm amplitude, by utilizing the finite element software Ansoft, the simulation about power output of Energyregenerative was performed, then the capacity of damping force produced by MRD under power output of Energyregenerative was simulated. The simulation results show that the Energyregenerative MRD can produce 1072N～2028N, at the vibration condition of low frequency and small amplitude, the energyregenerative MRD is able to change its damping characteristics without external power supply.
