Abstract
The utility model discloses an electromagnetic shock absorber, which is provided with a pair of homopolar and opposite upper electromagnetic body 5 and lower electromagnetic body 8 along the direction of a seismic focus; a permanent magnet 3 and the lower electromagnetic body 8 are arranged on the same supporting frame; a coil 7 which is not arranged on the supporting frame is fixed between the permanent magnet 3 and the lower electromagnetic body 8; the coil 7 is connected with the coil of the electromagnetic body 5 through a power amplifier 2. Following the acting force of shock, the utility model adjusts the acting force of the electromagnetic shock absorber. The utility model overcomes the technical defect of the rebounding shock of the existing shock absorber after buffered, and achieves the optimum effect of damping.
Description
Affiliated technical field
The utility model relates to a kind of vibration damper, especially the electromagnetic type vibration damper.
Background technique
Present vibration damper adopts spring or hydraulic system to reach the purpose of damping mostly, and its working principle is to compress afterwards earlier to rebound in the vibrations process, can only play the effect of damping vibration to a certain extent.Vibration damper itself can not overcome the technological deficiency of buffering back bounce-back vibrations.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of electromagnetic type vibration damper.
The technological scheme that its technical problem that solves the utility model adopts: along be provided with on the direction of earthquake source a pair of homopolarity relative on electromagnet 5 and following electromagnet 8, permanent magnet 3 places on the same support with following electromagnet 8, be not fixed between permanent magnet 3 and the following electromagnet 8 at the coil on the support 7, coil 7 links to each other with the coil of last electromagnet 5 through power amplifier 2.Be provided with diode 4 between coil 7 and the power amplifier 2.Between last electromagnet 5 and following electromagnet 8, be provided with spring 6.
The beneficial effects of the utility model are, can adjust the size of vibration damper active force along with the size of shock effect power, have solved the technological deficiency of bounce-back vibrations behind the existing buffer of damper, reach best damping effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
1. power supplys among the figure, 2. power amplifier, 3. permanent magnet, 4. diode is 5. gone up electromagnet, 6. spring, 7. coil 8. descends electromagnet.
Embodiment
Following electromagnet 8 on the direction of earthquake source and permanent magnet 3 move along with vibrations, coil 7 cutting magnetic lines produce induction current, induction current is behind diode 4 directional stream-guidances, enter the coil of electromagnet 5 through power amplifier 2 amplifying powers, induction current make magnetic field that electromagnet 5 produces not only polarity remain unchanged, and frequency is also identical, makes electromagnet 5 and following electromagnet 8 remain the same sex and repels each other.When permanent magnet 3 moved with following electromagnet 8, coil 7 flowed to when reducing to move down when the induction current of going up electromagnet 5 moves on being and increases, and made increase when reducing to move down when moving on the repulsion in upper and lower electromagnet magnetic field, reached the purpose of damping.Vibration damper quits work when preventing to cut off the power supply, and is provided with spring 6 between last electromagnet 5 and following electromagnet 8.
Claims (3)
1, a kind of electromagnetic type vibration damper, it is characterized in that: along be provided with on the direction of earthquake source a pair of homopolarity relative on electromagnet (5) and following electromagnet (8), permanent magnet (3) places on the same support with following electromagnet (8), be not fixed between permanent magnet (3) and the following electromagnet (8) at the coil on the support (7), coil (7) links to each other with the coil of last electromagnet (5) through power amplifier (2).
2, electromagnetic type vibration damper according to claim 1 is characterized in that: be provided with diode (4) between coil (7) and the power amplifier (2).
