Abstract
The invention discloses a double-faced magneto-rheological intelligent shock pad. The double-faced magneto-rheological intelligent shock pad iscomposed of magneto-rheological flat pads and an electromagnet array plate, wherein the electromagnet array plate is fixed between the two magneto-rheological flat pads; each magneto-rheological flat pad is made of a macromolecular elastic material and has N numbered cylinders with certain thickness, the upper bottom and the lower bottom of each cylinder are sealed by the macromolecular elastic or flexible material to form N munbered cylindrical cavities, and the N numbered cylindrical cavities are filled with magneto-rheological liquid; and the electromagnet array plate is composed of N numbered cylindrical electromagnets with the diameter less than or equal to that of the cylinder on the magneto-rheological pad. The current of each cylindrical electromagnet on the electromagnet array plate is changed to change the electromagnetic fields on both ends of each cylindrical electromagnet, so that the rigidity of the magneto-rheological flat pads on the two faces of the fixed electromagnet array plate is changed, thereby achieving the goal of shock absorption.
Description
Technical field
The invention belongs to a kind of damping pad, be specifically related to a kind of double-faced magneto-rheological intelligent shock pad.
Background technique
Common damping pad adopts rubber or macromolecular material to constitute, this class damping pad mainly is by the structure shape that changes damping pad or changes the damping property of damping pad in methods such as its surface and inner additional different materials, as: the disclosed two kinds of vibration attenuation pads of Chinese patent 200820183414.2 and Chinese patent 200620148742.X, although they all have certain damping property, also can be applicable to some vibration damping occasions, but owing in case its damping property after this class damping pad production moulding is just fixing and immutable, therefore, this class damping pad is difficult to satisfy the different requirements of different vibration damping occasions to the damping pad performance.
Summary of the invention
The present invention is directed to the unmodifiable deficiency of its damping property after the common damping pad machine shaping, a kind of double-faced magneto-rheological intelligent shock pad has been proposed, the damping property of double-faced magneto-rheological intelligent shock pad not only can change by the electric current that changes by magneto-rheological intelligent shock pad, but also can realize different damping properties in the zones of different on the magneto-rheological intelligent shock pad.
Technological scheme of the present invention is as follows:
Double-faced magneto-rheological intelligent shock pad is made of magnetorheological plain cushion and electromagnet array board, and the electromagnet array board is fixed between two magnetorheological plain cushions; Wherein, magnetorheological plain cushion is by what macromolecular material was made a certain thickness N cylinder to be arranged, the upper base of cylinder and go to the bottom employing high polymer elastic or N cylindrical cavity of flexible material sealing back formation, be full of magnetic flow liquid in N cylindrical cavity, N cylindrical cavity arranged the back that is shaped and adopted the macromolecule flexible material to cast the smooth plain cushion in two sides; The cylindrical electromagnet of drum diameter constitutes on the magnetorheological plain cushion and the electromagnet array board is less than or equal to by N, cylindrical electromagnet is to embed in the cylindrical shape soft iron be wound with electromagnetic coil on the excircle of cylindrical body soft iron after to constitute, and N cylindrical electromagnet arranged the back that is shaped and adopted non-magnet material to cast the smooth flat board in two sides; After the electromagnet array board was fixed between two magnetorheological plain cushions, the bottom surface of two cylindrical cavities on the electromagnet array board on the magnetorheological plain cushion of upper and lower surface corresponding with it of the two ends of each cylindrical electromagnet was concentric.
Function of the present invention is achieved in that
Each cylindrical electromagnet on the electromagnet array board of double-faced magneto-rheological intelligent shock pad with its up and down two cylindrical cavities that have been full of magnetic flow liquid on the corresponding magnetorheological plain cushion in two ends be a damper unit; Because of magnetic flow liquid is a kind of novel intelligent material, under the action of a magnetic field, continuous variation can take place in its viscosity, so, when cylindrical electromagnet feeds different electric currents, to produce the electromagnetic field of varying strength at cylindrical electromagnet two ends, this electromagnetic field make cylindrical electromagnet up and down the viscosity of the magnetic flow liquid in two cylindrical cavities on the magnetorheological plain cushion of two ends correspondence change, make cylindrical electromagnet up and down the rigidity of two cylindrical cavities on the magnetorheological plain cushion of two ends correspondence change and reach the purpose of vibration damping.Because a double-faced magneto-rheological intelligent shock pad is made of N such damper unit, if each damper unit is considered as " point " on the double-faced magneto-rheological intelligent shock pad, then the damping property of each " point " all can independent regulation on the double-faced magneto-rheological intelligent shock pad.Therefore, compare with the damping pad that adopts common rubber or macromolecular material to constitute, applicable scope is wider owing to the damping property equal energy independent regulation of each " point " on the double-faced magneto-rheological intelligent shock pad.
