The Design and Characteristic Analysis of New MR Fluid Damper
The structure principle and working model of the MR fluid damper using in the automotive suspension are described in this paper. It is concluded that the damping force is related to structure parameters, shear yield stress and viscosity of MR fluid through analysis result. As the effective length of damping channel under magnet field is restricted to the configuration of MR damper, a new MR damper with optimizing the damping channel of lord RD-1005-3 MR damper is presented and mechanical models are severally established for the two MR shock absorbers. It has been shown that the maximum damping force of new damper has dramatically increased comparing with the original one through external analysis.
