Embodiment Construction

[0015] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0016] see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , which is a specific structure of the present invention, a rocking magneto-rheological damper, which consists of a damping rod 6 installed in a damping tube 2, wherein: the damping tube 2 consists of 4 annular damping plates 1 and 3 spacer rings 5. A ring-shaped damping sheet 1 and a spacer ring 5 are combined in a concentric and plane-stacked manner and then fixed as a whole; the ring-shaped damping sheet 5 is made of a ring with four pairs (eight) of magnetic poles evenly distributed on the inner circumference. An electromagnet 8, and a layer of magnetorheological elastomer 4 with the same thickness is fixed on the end face of each magnetic pole of the ring electromagnet 8, and an excitation coil 3 is wound on each magnetic pole (see: Figure 4 and Figure 5 ); the spacer ring 5 is m...

Abstract

The invention discloses an oscillating type magnetorheological damper which is formed by the means that a damping rod is arranged in a damping pipe, wherein the damping pipe is combined and fixed into a whole by the means that N+1 ring-shaped damping fins and N spacer rings are concentrically overlapped with one another one by one in the plane; each ring-shaped damping fin consists of a ring-shaped electromagnet and magnetorheological elastomers, wherein at least three pairs of magnetic poles of the ring-shaped electromagnet are uniformly distributed at the inner periphery, and the nagnetioreological elastomers with the same thickness are respectively fixed on the end surface of each magnetic pole of the ring-shaped electromagnet; each spacer ring is made from non-magnetic permeability material, the outer diameters of the spacer rings are as the same as those of the ring-shaped damping fins, and the inner diameters of the spacer rings are not less than those of the magnetic poles of the ring-shaped electromagnets; and the damping rod is in the shape of a cylinder which is made from high-magnetic permeability material, and the length of the damping rod is not less than that of the damping pipe.

Description

technical field [0001] The invention belongs to a damper, in particular to a swinging magnetorheological damper. Background technique [0002] Shaking is a complex movement, and people usually use multiple dampers to combine it to reduce vibration, but this will make the vibration damping structure very complicated, so people design independent dampers for three-dimensional shaking , such as: Chinese Patent Application No.: 2010105878118 "Shaking Magneto-Rheological Damper", although this kind of magnetorheological damper can be used for shaking vibration reduction occasions, once the magnetorheological fluid leaks or The sedimentation of the magnetorheological fluid will lead to the degradation or failure of the performance of the magnetorheological damper. Contents of the invention [0003] In order to overcome the defects of the existing oscillating magnetorheological damper, the present invention proposes an oscillating magnetorheological damper. [0004] The techni...
