Damping Characteristics Modeling and Simulation of MR Damper

The magnetic rheology damper existence to precipitate, superheat, the magnetic field efficiency low, service difficulty as well as the structure is complex, the high construction cost, and the low reliable, has affected the magnetic rheology damper project application and service life seriously. In order to realize the multi-degree of freedom vibration control, and overcomes precipitate and radiation questions and so on, has designed one kind new magnetic rheology damper, might adapt in the multi-degree of freedom vibration control. The damper has used the fission type structural design, solved the precipitate, the structure radiates, the wiring difficulty, structure complex and so on the questions, has easily to install, to radiate, the structure simply, the higher efficiency merits. And based on the Bingham model to carry on the modeling of MR damper, used Simulink to carry on the simulation, has analyzed the controlling current, the excitation frequency and the oscillation amplitude to the damping characteristic influence.
