Abstract
A novel adjustable magnetic fluid damper is designed in this paper that dissipates the vibration energy by viscous flow of magnetic fluid with movement of inertia mass. First, considering the viscosity of magnetic fluid and the size of the damper, the theoretical model of the magnetic mechanical coupling system is established, and the flow velocity of the damper can be obtained from this model. Second, based on the magneto-viscous characteristic of magnetic fluid, the numerical simulation model of the cantilever and damper system is established. The distribution of magnetic field in the damper is studied. Finally, the displacement response and frequency response of the freely supported beam are calculated, and the flow distribution of the magnetic fluid in the damper is analyzed. This damper can finely adjust the damping parameters, and has good damping effect on the vibration of low frequencies and small damping.
