N2 - A novel adjustable magnetic liquid damper is designed in this paper which dissipates the vibration energy by viscous flow of magnetic liquid with movement of inertia mass. Firstly, considering the viscosity of magnetic liquid and the size of the damper, the theoretical model of the magnetic mechanical coupling system is established, and the damping force of the damper can be obtained from this model. Secondly, the magnetic field distribution in the absorber is calculated by the finite element method. Based on the magneto-viscous characteristic of magnetic liquid, the numerical simulation model of the cantilever and damper system is established. The dependence of damping force on magnetic field and the size of inertial mass is analyzed. Finally, the dependence of damping force on magnetic field and the size of inertial mass is analyzed. This damper can finely adjust the damping parameters, and has good damping effect on the vibration of the spacecraft structures with low frequency and small damping.
