Description

Technical Field

[0001] The invention relates to the field of dampers, and in particular to a magnetorheological damper. Background Art

[0002] A magnetorheological damper is a device that reduces mechanical vibration by changing the viscosity of a liquid. Under a high magnetic field, a magnetorheological damper uses the controllable rheological properties of a magnetic fluid to change the damping. The inside of the magnetorheological damper is filled with a magnetic fluid. When the electromagnetic coil is energized, a strong magnetic field is generated, causing the magnetic fluid to undergo rheological phenomena. During the rheological period, the magnetic fluid forms a large number of chain structures and mesh structures, which will create resistance to movement in the direction of motion. As the current continues to change, the magnetic field becomes weaker and weaker, and the magnetic fluid gradually returns to a liquid state, thereby changing the damping value.
