Become liquid under magnetic fields, the yield strength for flowing through the magnetorheological fluid of fluid course changes, to export damping force, and can
To change the shear yield strength of magnetorheological fluid by control magnetic field strength, the stepless of the damping force of MR damper is realized
It adjusts.
General magnetorheological device is a kind of novel semi-active damper device based on magnetorheological fluid controllable characteristics, the device
Resistance can be generated to movement, and is used to the energy of dissipation movement, and fast response time, structure letter are possessed in its working range
It is single, small in size, be easy to control and low power consumption and other advantages, be a kind of ideal vibration isolation, antishock device, in building, machinery, military project etc.
Aspect has wide application prospect, when magnetorheological device is applied to automotive suspension, can effectively play damping effect, but use
The disadvantages of magnetorheological fluid is that there is sealing difficulties is big for the device of damping medium, and system structure is complicated, at high cost, therefore design one
The magnetic rheological vibration damper simple and effective, that seal request is low of kind has broad application prospects.
