The invention discloses a three-way magneto-rheological dynamic vibration absorber which comprises a magneto-rheological vibration absorber body, and the magneto-rheological vibration absorber body comprises a one-way magneto-rheological vibration absorber body and a two-way magneto-rheological vibration absorber body. The one-way magneto-rheological vibration absorber is arranged on the seat through a connecting piece and used for absorbing vibration of the seat in the Z direction, the magnetic field intensity is controlled by controlling the current of the magnet exciting coil, the shear stress is changed, and damping adjustment is achieved. The two-way magneto-rheological vibration absorber is arranged on the one-way magneto-rheological vibration absorber through the cross beam and used for absorbing vibration of the seat in the X direction and the Y direction, the magnetic field intensity is controlled by controlling the current of the magnet exciting coil, and rigidity adjustment is achieved. The one-way magneto-rheological vibration absorber and the two-way magneto-rheological vibration absorber jointly achieve absorption of vibration of the seat.
本发明公开了一种三向磁流变动力吸振器,包括磁流变吸振器,磁流变吸振器包括单向磁流变吸振器和双向磁流变吸振器。单向磁流变吸振器通过连接件设置于座椅,用于吸收座椅沿Z向的振动,通过控制励磁线圈的电流大小控制磁场强度,改变剪切应力,实现阻尼的调整。双向磁流变吸振器通过横梁设置于单向磁流变吸振器,用于吸收座椅沿X和Y向振动,通过控制励磁线圈的电流大小控制磁场强度,实现刚度的调整。单向磁流变吸振器和双向磁流变吸振器共同实现座椅振动的吸收。
