TMD is made of mass block, elastic element, the big component of damping element three, and maximum component is inertia mass.Inertia matter
The key technology that the supporting way in main structure is TMD device is measured, it need to guarantee that inertia mass and the main structure vibration shape are humorous
Center of percussion has determining natural vibration period and damping.The inertia mass of TMD system can using multistage pendulum, inverted pendulum, hydraulic support system,
The suspension such as laminated rubber bearing or support.
The common system supported using track, then require track to have enough rigidity, cannot when supporting inertia mass
There is biggish deformation, excessive resistance caused by not sliding because of inertia mass.In addition, generally exist can not by the TMD of track support
The friction avoided, to TMD, there is adverse effects for friction: 1, when dynamic excitation smaller, i.e., structure be in microvibration, TMD
The inertia force of exercise quality block is possible to that its stiction can be less than, so that it is in the lock state TMD, TMD also just temporarily funeral
The function of energy-obsorbing and damping is lost；2, when controlled structures are had the load action of shock feature by earthquake etc., excessive friction
It can delay the starting time of TMD, significantly so as to cause the decline of control effect.
Existing TMD technology has the following problems: external small excitation, which can not start, to play a role；It simultaneously cannot be according to structure
Different directions vibration frequency tunes vibration damping.

To achieve the above object, the utility model provides the following technical solutions: a kind of electromagnetic levitation type universal type level tuning
Mass damper, including vertical ring flat-plate, horizontal base, fixing piece, damper, spring, mass block and mass block pedestal, it is described perpendicular
Integral support is formed to ring flat-plate and horizontal base, bracket is fixed in building structure by fixing piece, is set in the horizontal base
It is equipped with pit, mass block pedestal is provided in the pit, mass block pedestal upper end is provided with mass block, the mass block
Damper and spring are connected between pedestal and vertical ring flat-plate, the horizontal base and mass block pedestal are permanent magnet, two bases
Seat opposite face magnetism is identical.
Preferably, the vertical ring flat-plate is made of metal, rounded or oval.
Preferably, the horizontal base is rounded or oval.
Preferably, the mass block pedestal evagination and horizontal base pit adaptation.
Preferably, the spring is metal material structure or electromagnetic type material-structure.
Preferably, the spring and damper are arranged in pairs, at least 3 pairs, symmetrically radially arranged.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model solves in the smaller situation of external drive that TMD cannot start by magnetic suspension design, Bu Nengfa
The problem of waving effect, while vibration frequency that can be different according to controlled structures different directions, adjustment respective direction TMD vibration frequency
Rate reaches the optimum efficiency of comprehensive tuning vibration damping.
2, the utility model structure is simple, cheap, is simple to manufacture, and transports and easy for installation, functional, satisfaction makes
Use demand.
