Controller 34, controller 34 are connected with electromagnetic induction coil and acceleration transducer 32, and controller 34 is to acquire acceleration sensing
The acceleration signal that device 32 transmits, is handled by analysis, and the electric current of electromagnetic coil 33 is input to control, is acted on to change
Magnetic field intensity on magnetic rheology elastic body realizes the real-time control of magnetic rheology elastic body.
Cylinder base attachment device is mainly by homopolar magnet (the first magnetic substance 41 and the second magnetic substance 42), rigid damping block
46, spring 47, fixing screws, sliding bearing, pressing plate, connector composition.Connector and the first magnetic substance 41 are rigidly connected,
In, the first magnetic substance 41 is fixed on sliding bearing, and sliding bearing is fixedly connected by pressing plate with rigid damping block, wherein hardness
Damping block is slightly above fixing screws, and rigid damping block is fixed on spring, rigid damping block and spring pocket in fixing screws, Gu
Determine screw to be rigidly connected with compressor case, wherein rigid damping block is designed as pie structure, spring rate is larger, plays slight
The effect of buffering.
The specific implementation process of the invention：It is powered to linear electric motor primary winding 52,53 bilateral reciprocation of secondary mover,
Since secondary mover 53 and piston 60 are directly rigidly connected, thus with 60 bilateral reciprocation of piston, and then compress by air inlet
The cold media gas that pipe 70 is input by air inlet 21, inlet chamber 22, intake valve 221 compresses the cold media gas of end of a period by exhaust
Valve 231, discharge chamber 23 further arrive exhaust pipe 80 and are exhausted, to complete a working cycles of cold media gas.But this
The piston compressor of structure will produce vibration horizontally and vertically in the process of running, and what is be especially horizontally oriented shakes
It is dynamic particularly strong.When piston compressor is run, in the horizontal direction, the acquisition in real time of controller 34 is mounted on adding on cylinder body 20
32 signal of velocity sensor, controller 34 are handled by analysis, to calculate the real-time control needed for magnetic rheology elastic body this moment
Electric current is made to act on the magnetic field intensity on magnetic rheology elastic body and is changed by the size of current of change electromagnetic coil 33, into
And change the physical aspect of magnetic rheology elastic body internal magnetization particle, so that the damping size of magnetorheological elasticity changes, from
And realize the real-time control to generating horizontal vibration during this compressor operating, it is more steady when making compressor operating.
On the other hand, in order to meet the needs of horizontal direction total movement, cylinder base attachment device is carried out
Special design, being rigidly connected below connector has same polarity magnet, and the first magnetic substance 41 is rigidly connected with sliding bearing, together
41 left and right ends of the first magnetic substances of Shi Tong are designed with another two piece of second magnetic substance 42, in compressor operating, the first magnetic substance
While 41 horizontal sliding, utilized since the effect of the second magnetic substance 42 can also play magnetic force bigger round about,
Make vibration smaller, even if stable correct position can be played the role of if in the case of without motion.
In vertical direction, rigid damping block is mounted on the upper surface of spring, and when having small vibration, rigid damping block can be with
Vibration damping, spring play the role of buffering, and the two is used in combination, and keeps effectiveness in vibration suppression more preferable.
The present invention also provides a kind of refrigeration equipment, including compressor, compressor is above-mentioned compressor.
