Abstract
The utility model discloses an electromagnetic vibration damper which comprises a fixing base (3), a vibration body (2) is arranged on the fixing base (3) and provided with a coil (1), a magnet (4) is arranged on the lower face of the coil (1), and the two ends of the coil (1) are connected with a branch circuit (6) through wires (5). The electromagnetic vibration damper is simple in structure, convenient to operate, free of contact or mechanical friction or abrasion and long in service life and does not need lubricating, and the rigidity and damping are controllable. The electromagnetic vibration damper has good economy and reliability and can be widely used for the problem of vibration control in engineering.
Description
Technical field
The utility model relates to a kind of electric and magnetic oscillation damper, and particularly a kind of half active vibration is controlled and used the electric and magnetic oscillation damper.
Background technique
Along with the raising of people's living standard, living environment has on every side also more and more been paid attention to.Especially, the vibration noise source that produces in the develop rapidly process of industry has brought very large harm for our living environment and health.Therefore the control to vibration is significant, by the control to vibration: in life, can reduce the noise pollution degree of periphery, for people provide the relatively good environment of living; At work, can reduce vibration apparatus to the impact of workman's health and reduce operating irregularity, for the vast labourer who works in rugged environment provides healthier working environment; In engineering, can extend the life-span of all kinds of machineries, reduce the economic loss of enterprise on engineering apparatus and equipment.We can utilize vibration on the one hand in the process of controlling vibration, to vibrate as a power source, realize the function of various vibratory equipments, as the manufacturing mechanism that occurs successively nearly decades: vibration transmission, vibration screening, vibro-grinding, vibropolish, pile vibrosinking, noise weeding etc., impel the vibration trend to favourable one side in life and engineering; Another kind is to the inhibition of vibration, by certain means, makes the level of vibration of controll plant meet people's pre-provisioning request, such as sqouynd absorption lowering noise, liquid-springing, precision type instrument vibrationproof etc., thereby can not decay for the vibration that the mankind utilize.
The model utility content
The purpose of this utility model is, a kind of electric and magnetic oscillation damper is provided.The utlity model has simple in structure and characteristics convenient operation.
The technical solution of the utility model: a kind of electric and magnetic oscillation damper is characterized in that: comprise fixed base, fixed base is provided with oscillating body, and oscillating body is provided with coil, is provided with magnet below coil, and the two ends of coil are connected with branch circuit by wire.
In aforesaid electric and magnetic oscillation damper, described coil is pasted the end at oscillating body.
In aforesaid electric and magnetic oscillation damper, the center line of described coil and magnet is on a horizontal line.
In aforesaid electric and magnetic oscillation damper, described magnet is columned permanent magnet.
In aforesaid electric and magnetic oscillation damper, described branch circuit is a resistance.
In aforesaid electric and magnetic oscillation damper, described branch circuit is a resonance circuit.
Compared with prior art, drive the coil that is attached to the oscillating body side during vibration of oscillating body in the utility model and vibrate together, because the change of magnetic flux makes in coil, produce induction electromotive force, corresponding generation induction current.Branch circuit is used for the electric current that the storage induction field produces, and by the form of resistance with heat energy, distributes, thereby reduces the induction current between coil and magnet, reduces the vibration frequency of oscillating body, reaches the purpose of controlling vibration.The utility model is simple in structure, and convenient operation has non-contact, machinery-free friction and wear, need not lubricate, the life-span is long and rigidity and the advantage such as damping is controlled, has good Economy and reliability.The utility model can be widely used in the vibration control problem on engineering.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-coil, 2-oscillating body, 3-fixed base, 4-magnet, 5-wire, 6-branch circuit.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of electric and magnetic oscillation damper, form as shown in Figure 1, comprises fixed base 3, and fixed base 3 is provided with oscillating body 2, and oscillating body 2 is provided with coil 1, is provided with magnet 4 below coil (1), and the two ends of coil 1 are connected with branch circuit 6 by wire 5.
Described coil 1 is pasted the end at oscillating body 2.
The center line of described coil 1 and magnet 4 is on a horizontal line.
Described magnet 4 is columned permanent magnets.
Described branch circuit 6 is a resistance.
Described branch circuit 6 is resonance circuits.
Working principle of the present utility model is as follows: drive the coil be attached to the oscillating body side while by oscillating body, vibrating and swing, produce induction electromotive force, corresponding generation induction current because the change of magnetic flux makes in coil this moment.At the electric current of storing the induction field generation by branch circuit, and by the form of resistance with heat energy, distribute, thus the induction current between reduction coil and magnet, and the vibration frequency of reduction oscillating body, reach the purpose of controlling vibration.
