Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of self-magnetic tuning vibrating absorber.
Background technique
Traditional vibration damper has spring and fluid damping formula.Spring utilizes its elastic recovery properties to realize vibration damping, and still, spring damping is easy to generate exciting and fatigue, and the high frequency damping property is poor, also produces noise during work; The fluid damping formula is made up of the cylinder barrel of piston that has flowing hole and cooperation with it, piston by a rod member with connected by damping body, fluid (oil, gas or other flowing medium) is housed in cylinder barrel, during piston motion, fluid produces damping force to piston and realizes vibration damping by flowing hole, but this vibration damper, damping force changes limited, and also difficulty is applicable to dither, and fluid easily leaks.In recent years, multiple magneto vibration damper has appearred, improved the performance of traditional vibration damper to some extent, but following defective is arranged: 1. utilize two repulsion between the permanent magnet same polarity to realize vibration damping, this vibration damper requires permanent magnet that high coercivity is arranged in order to avoid demagnetization, but the rare earth permanent magnet Curie temperature of high-coercive force is low at present, can't adapt to hot environment; 2. the magnetic line of force in the magnetic repulsion type vibration damper is laterally extruded from axial running clearance because of repelling each other, and can't form the closed-loop path, and leakage field is very big, befouling environment; 3. each magneto vibration damper damping parameter is fixed, and can only be applicable to the vibration damping to the oscillating body of known vibration parameters, can't adapt to the vibration damping of the oscillating body that vibration parameters is constantly changed.
Summary of the invention
The utility model designs a kind of self-magnetic tuning vibrating absorber, can overcome the defective of above-mentioned traditional vibration damper and existing magneto vibration damper, vibrational energy can be converted to useful electric energy, can regulate the damping parameter value according to the vibration parameters of the body that shakes, and cost be low, non-maintaining, the life-span is long.
The utility model is realized by following technological scheme.
The utility model is made up of stator, mover and control system.Gappedly between stator and the mover do not contact.The annular permanent magnet of radial magnetizing all is set in stator and mover, and the stator ring permanent magnet radially opposite pole is relative with the mover annular permanent magnet, the stator ring permanent magnet is coaxial with the mover annular permanent magnet; Between stator and mover inductor coil is set, the interior circle of inductor coil and stator ring permanent magnet is fixed.At mover the adjusting field coil is set, its interior circle with the mover annular permanent magnet unshakable in one's determination is fixed.Control system is made up of inductor coil, adjusting field coil, rectification voltage regulator, storage battery, vibration transducer and regulator.Described stator and mover can be changed mutually according to practical application, and promptly stator is as mover, and mover is as stator.During use mover with connected by damping body, stator connects with fixed base.
During the utility model work, relative displacement takes place in stator and mover vertically, because magnetoresistive effect, the cylindrical of the interior circle of the magnetic conduction annulus of stator and the magnetic conduction annulus of mover produces oblique pulling mutually, oblique pulling is decomposed into radial and axial power, radial force offsets, and axial force is the damping force that vibration damping needs; Stator and mover take place vertically relative displacement the time, produce induction current at inductor coil, this electric current charges a battery or directly use through rectification voltage regulator, simultaneously, the magnetic field of being known this electric current by Lenz's law hinders stator and mover relative displacement, and obstruction power also is the damping force that vibration damping needs.The magnetic intensity that the magnetic field that field coil produces is used for regulating mover makes mover change generation optimum damping parameter value by the vibration of oscillating body, thereby obtains best effectiveness in vibration suppression.Field coil by regulator from the storage battery power taking, regulator according to vibration transducer obtain by the oscillating signal of damping body, regulate the size of supplying with the field coil electric current, regulate magnetic field thereby produce.
The utlity model has existing all advantages of magneto vibration damper, and also have following advantage:
1. the utility model utilizes stator and mover permanent magnetic gravitation to realize vibration damping, and it is not very high that the coercivity of permanent magnet is required, and has enlarged the scope of choosing permanent magnet; And because stator and mover attract magnetic flux to pass formation closed-loop path, gap, so leakage field is very little, environmental pollution is little.
2. utilize inductor coil that vibrational energy is converted to available electric energy, rather than resemble spring piston formula vibration damper or some magneto vibration damper and with friction mode vibrational energy is converted to thermal waste and falls.
3. the utility model utilizes permanent magnetic field, induced electromagnetic field and regulates magnetic field and forms damping power simultaneously, and damping property is more excellent, and effectiveness in vibration suppression is better.
4. not necessarily very high to the coercivity requirement of permanent magnet, under guaranteeing that remanent magnetism requires, can select the permanent magnet of high-curie temperature; Any one party is provided with the annular permanent magnet of axial charging in stator and mover, and the opposing party is provided with and the parallel vertically relative magnetic guiding loop of annular permanent magnet, and a side that will be in high temperature in actual applications is provided with magnetic guiding loop, and the opposing party is provided with annular permanent magnet.Owing to these two reasons, the utility model can the higher environment of adaptive temperature.
