Magnetic liquid tuned mass damper utilizing particle collision damping

The invention discloses a magnetic liquid tuned mass damper utilizing particle collision damping, and belongs to the field of vibration control. The problem that an existing magnetic liquid tuned mass damper cannot be applied to medium-high frequency vibration is successfully solved. The tuned mass damper comprises a shell (1), a left return permanent magnet (2), left supporting magnetic liquid (3), a left supporting permanent magnet (4), inner cavity magnetic liquid (5), right supporting magnetic liquid (6), a right supporting permanent magnet (7), a right return permanent magnet (8), a right exciting coil (9), a ball body (10), a Hall element (11), a supporting shell (12), an air duct (13) and a left exciting coil (14). According to the tuned mass damper, magnetic liquid damping and particle collision damping are combined, active control is introduced at the same time, and the tuned mass damper is suitable for low-frequency vibration within 10 Hz and has the effect on high-frequency vibration above 100 Hz.
