Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings:
As Figure 1-5, a kind of novel pendulum-type eddy current tuned mass damper of the utility model, including pillar 1, screw 2nd, supporting plate 3, ball pivot 4, rigid rod 5, combination quality block 6, magnet 7, arc copper coin 8, magnetic conductive board 9, support base 10, described spiral shell Nail 2 is affixed to pillar 1 and supporting plate 3 together through the hole on the side of supporting plate 3, and described supporting plate 3 is equidistant provided with 4 Ball seat hole, the described outer surface of ball pivot 4 is engaged with the ball seat hole in supporting plate 3, the upper end of described rigid rod 5 and ball Hinge 4 is fixed together, and lower end is fixed together with combination quality block 6, and the upper end of described combination quality block 6 is cuboid 601, Lower end is cylinder 602, and the lower section of cylinder 602 is provided with spherical surface hill 603, and described magnet 7 is connected in spherical surface hill 603 Lower surface on, the N poles and S poles of described magnet 7 are spaced, and described arc copper coin 8 is being arranged on combination quality block 6 just Lower section, the curved upper surface of described magnetic conductive board 9 is connected with the lower surface of arc copper coin 8, and the upper end of described support base 10 is consolidated Surely the bottom surface of magnetic conductive board 9 is arrived, lower end is fixed on ground by foundation bolt.
Described support base 10 includes upper connecting portion 1001, threaded post 1002, open tubular column 1003, lower connecting portion 1004, institute The upper surface for the upper connecting portion 1001 stated and the bottom surface of magnetic conductive board 9 are fixed together, the upper end of described threaded post 1002 with The lower end of upper connecting portion 1001 is connected, and the described lower end of open tubular column 1003 is connected with the upper end of lower connecting portion 1004, described The lower end of threaded post 1002 is provided with external screw thread, and described open tubular column 1003 is provided with to be engaged with the external screw thread in threaded post 1002 Internal thread.
The diameter of described ball pivot 4 is less than the diameter in the ball seat hole in supporting plate 3, the upper surface of described arc copper coin 8 There is certain interval between the lower surface of magnet 7, and the gap is kept during combination quality block 6 is swung with moving magnet 7 It is constant.
When the structure (generally skyscraper) being made up of pillar 1 and supporting plate 3 vibrates because wind action is produced, Vibration can be delivered to the swing that combination quality block 6 causes combination quality block 6 by ball pivot 4 and rigid rod 5, now with combination quality The magnet 7 and arc copper coin 8 that block 6 is connected produce the current vortex produced in electromagnetic induction, arc copper coin 8 and produced and magnet 7 itself The opposite electromagnetic field of polarity of the magnetic field, the electromagnetic field that newly produces hinders the swing of combination quality block 6, the potential energy of combination quality block 6 and Kinetic energy is converted into the heat energy that current vortex generates heat in arc copper coin 8, and heat energy finally scatters and disappears in atmosphere, the pivot angle of combination quality block 6 Can be less and less, eventually stop.The connection between plate 3 and rigid rod 5 is supported using ball pivot 4, is greatly reduced The frictional damping between ball seat hole and ball pivot 4 in supporting plate 3, improves service life so that combination quality block 6 is under micro- shake Also vibration signal can be received.In the swing process of rigid rod 5, between the upper surface of arc copper coin 8 and the lower surface of magnet 7 Gap keeps constant, is conducive to keeping the stability of damped coefficient.By dismantling the lower margin spiral shell that support base 10 is connected with ground Bolt, rotates open tubular column 1003 so that the distance between threaded post 1002 and open tubular column 1003 increase or reduced, and then cause arc Gap increase or reduction between the upper surface of shape copper coin 8 and the lower surface of magnet 7, so as to the size of eddy-current damping effect It is adjusted.Due to combination quality block 6 quality much larger than arc copper coin 8 and magnetic conductive board 9 quality and, therefore pass through and change branch Support the height of seat 10 and change arc copper by adjusting the length of rigid rod 5 to adjust the gap-ratio between arc copper coin 8 and magnet 7 Gap between plate 8 and magnet 7 will more facilitate, laborsaving, can effectively reduce human cost, improve operating efficiency.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation Example, all any change done based on the utility model or modification belong to the claimed scope of the utility model.
