Embodiment 1

[0035] like Figure 5-Figure 6 As shown, a single-degree-of-freedom eddy current tuned mass damper for wind power includes a bracket 1, and the bracket 1 includes a first horizontal connector 11, a second horizontal connector 12 and a vertical connector 14, and the second horizontal connector 12 Located below the first horizontal connecting member 11, the second horizontal connecting member 12 and the first horizontal connecting member 11 are both horizontal structural members, and they are arranged in parallel. The two vertical connectors 14 are respectively connected to two ends of the first horizontal connector 11 and the second horizontal connector 12 . Preferably, in this embodiment, the first horizontal connecting piece 11 , the second horizontal connecting piece 12 and the vertical connecting piece 14 are rods.

[0036] The bottom surface of the first horizontal connector 11 is fixedly equipped with a conductor plate 2, the top surface of the second horizontal connecto...

Embodiment 2

[0041] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that a second spring 9 is added in this embodiment. set diagonally between. By setting the second spring 9, a certain spring stiffness can be provided, the size of the first spring 8 can be reduced, and the installation space of the first spring 8 can be further reduced, which further facilitates the installation of the eddy current tuned mass damper on the wind power generation tower. Install.

Embodiment 3

[0043] like Figure 1-Figure 4 As shown, an eddy current tuned mass damping system includes two single-degree-of-freedom eddy-current tuned mass dampers for wind power as described in Embodiment 1, and two wind power single-degree-of-freedom eddy-current tuned mass dampers The linear guide rails 6 are arranged orthogonally, and two single-degree-of-freedom eddy current tuned mass dampers for wind power are arranged at intervals in the vertical direction. That is: one of the linear guide rails 6 is arranged along the transverse direction, and the other linear guide rail 6 is arranged along the longitudinal direction, so that one mass block 3 slides along the transverse direction, and the other mass block 3 slides along the longitudinal direction, and the moving directions of the two mass blocks 3 are perpendicular to each other , can damp the vibration in both directions of the horizontal plane of the wind power generation tower, and by arranging the two single-degree-of-freedo...

Abstract

The invention discloses a single-degree-of-freedom eddy current tuned mass damper and damping system for wind power. The damper comprises a support, the support comprises a first horizontal connecting piece and a second horizontal connecting piece, the second horizontal connecting piece is located below the first horizontal connecting piece, and a conductor plate is fixedly installed on the bottom face of the first horizontal connecting piece; a linear guide rail is arranged on the top face of the second horizontal connecting piece and horizontally arranged, a mass block is arranged between the first horizontal connecting piece and the second horizontal connecting piece, magnetic steel is fixedly connected to the top face of the mass block, the magnetic steel and the conductor plate are arranged at intervals, and pulleys are arranged on the bottom face of the mass block and can slide along the linear guide rail. The support is provided with a reversing device, the mass block is connected with a pull rope, the pull rope penetrates through the reversing device and then is connected with a first spring, and the first spring is vertically arranged. According to the single-degree-of-freedom eddy current tuned mass damper and damping system for the wind power, springs which should be horizontally arranged originally can be vertically arranged through the reversing device, and therefore the horizontal installation space of the eddy current tuned mass damper is reduced.

Description

technical field [0001] The invention relates to a damper, in particular to a single-degree-of-freedom electric eddy current tuned mass damper and a damping system for wind power. Background technique [0002] A damper is a device that uses damping characteristics to slow down mechanical vibration and consume kinetic energy. There are three main types of dampers: liquid dampers, gas dampers and electromagnetic dampers. After development, dampers are widely used in aerospace, aviation, military, guns, automobiles and other industries. Traditional buffer devices are generally mechanical and hydraulic. The principle of these two buffer devices is to convert structural kinetic energy into heat energy through contact mechanical friction, which is used to prolong the impact time of the impact load and absorb and convert the energy of the impact load. . However, the mechanical friction damper has the problem of large starting friction, while the liquid damper has oil leakage; in ...
