| Abstract: | Based on the performance of Magnetic rheological (MR) fluid and the structural characteristics of foam metal,a new type of MR damper is proposed by combining the MR fluid and foam metal.The damping force model of the damper and the nonlinear mathematical model of vibration reduction system are established.Vibration reduction performance of MR fluid damper is validated through experimentation.The result indicates that the proposed nonlinear model could accurately express the damping force and vibration reduction performance of the MR fluid damper.Within some range of parameters,this kind of MR fluid damper can meet the different requirements for damping of vibration system. |
