The magnetorheological damper comprises a working cylinder body module, an imporous cylinder body cover, a porous cylinder body cover, a piston module, a working clearance, magnetorheological fluid and a power source. The working cylinder body module comprises a working cylinder inner core, a coil and an electric field shielding layer. The working cylinder inner core is a hollow cylinder, and the internal diameter of the working cylinder inner core linearly changes along the axis of the working cylinder inner core. The working clearance is the clearance between the outer circumferential wall of a piston and the inner circumferential wall of the working cylinder inner core and changes along with the position difference of the piston. The variable-damping magnetorheological damper is reasonable in structure and large in damping force adjusting range, the variable working clearance is achieved through a variable cylinder body, and fluid viscosity is controlled through the power source.

Background technique
MR damper is a kind of half active damping instrument, is widely used in, in the structural vibration reduction control fields such as automobile, bridge, building, having important effect to structural vibration reduction.Existing MR damper is by the applying of external magnetic field, and the viscosity of alter, makes magnetic flow liquid obtain different damping forces by the working clearance between piston outer periphery wall from clutch release slave cylinder inner circle wall.Although existing MR damper achieves mutative damp, but still there is certain shortcoming: the working clearance between piston outer periphery wall and clutch release slave cylinder inner circle wall is constant, the change of damping force places one's entire reliance upon the change of external magnetic field, therefore the regulation range of damping force is difficult to expand.
Summary of the invention
The technical problem that the present invention need solve is: the problems such as damping force regulation range is limited existed for prior art, the invention provides a kind of rational in infrastructure, adopt and become cylinder body and realize becoming working clearance, Energy control fluid viscosity, the great mutative damp MR damper of damping force regulation range.
In order to solve the problem, the solution that the present invention proposes is: single pole becomes cylinder body active single control mutative damp MR damper, and it comprises working cylinder module, atresia cylinder body lid, is free cylinder body lid, piston modules, working clearance, magnetic flow liquid, power supply.
Described working cylinder module comprises clutch release slave cylinder inner core, the coil be installed on described clutch release slave cylinder inner core excircle, be installed in the electric field shielding layer of described coil outer.
Described clutch release slave cylinder inner core is hollow cylinder, and the middle part internal diameter perpendicular to axis is maximum, and two ends internal diameter is minimum, and internal diameter changes along its axis linearity.
Described atresia cylinder body lid, be free cylinder body to mount cover the two ends being located at described working cylinder module, described piston modules is installed in the inside of described working cylinder module; Described piston modules comprises piston rod, is installed in the piston of described piston rod left end, is opened in pilot hole symmetrical on described piston, two be parallel to described piston rod and be installed in described atresia cylinder body lid by described pilot hole and be the guide rod between free cylinder body lid; There is free cylinder body to cover described in described power supply is installed in, and be connected with described coil by wire; Described clutch release slave cylinder inner core, atresia cylinder body lid, be free cylinder body lid to surround enclosed space in be full of described magnetic flow liquid; The described piston rod the other end, by seal arrangement, the bearing be installed in bearing hole, reaches the outside of described working cylinder module.
Described clutch release slave cylinder inner core is divided into left and right two-part by described piston, and described magnetic flow liquid is by working clearance left and right flowing; The described working clearance is the gap between the periphery wall of described piston and the inner circle wall of described clutch release slave cylinder inner core, and the position with described piston is different and change.
Compared with prior art, the invention has the advantages that: single pole of the present invention becomes cylinder body active single control mutative damp MR damper and is provided with clutch release slave cylinder inner core and hot-wire coil, with the change of piston position, the working clearance between piston outer periphery wall and clutch release slave cylinder inner core inner circle wall changes.It can thus be appreciated that the present invention is rational in infrastructure, by changing the working clearance and fluid viscosity jointly realizes mutative damp, expanded damping force excursion.
