Specific implementation mode
Illustrate the specific implementation mode of the present invention below.
As shown in Figure 1 and Figure 2, pipeline magnetic suspension active damper is by being coated on pipeline periphery and in positioned opposite upper
Half part and lower half portion are constituted；As shown in Figure 1 and Figure 2, above-mentioned top half includes shell 1 with lower half portion, in shell 1
Inside external limiter 2 and internal limiter 5 are sequentially set, in shell 1, external limiter 2 and internal limiter 5 it
Between also set up sliding bearing 3, in the piston 7 that is slidably connected in sliding bearing 3, in magnet exciting coil 4 is arranged in piston 7；In shell 1
It is interior, in the inside of the internal limiter 5 also affixed permanent magnet 6 for coordinating with tubing giving sufficient strength periphery to be controlled.
Sliding bearing 3 is that the left sliding bearing being arranged symmetrically centered on the axis of shell 1 and right sliding bearing form, on
It is annular hollow piston to state piston 7, and sliding bearing 3, permanent magnet 6 are loop configuration.Top half and lower half in the present invention
It is to facilitate installation, and each sliding bearing 3 is divided into as left sliding bearing, right sliding bearing then that sliding bearing 3 is arranged in part
Be in order to when piston 7 be excited coil 4 drive move up and down generate transfinite displacement when by internal limiter 5, external limiter 2
Pooling feature play a protective role to structure of the invention.
In the present invention external limiter 2 and internal limiter 5 for when avoiding magnet exciting coil 4,7 stroke of piston excessive with
Shell 1 generates rigid contact, can be required in the present invention to magnet exciting coil 4 and permanent magnet according to the vibration control of pipe-line system
6 number of poles is configured, such as one group of magnet exciting coil 4 can control the vibration in a direction, two groups of magnet exciting coils with permanent magnet 6
4 can control the vibration of any direction in circumferential plane with permanent magnet 6 using principle of vector control.
The specific implementation process of the present invention is as follows：
As shown in figure 3, controller obtains what needs controlled by acquiring, handling the pipeline vibration data of accelerometer measures
Pipeline vibration direction and amplitude, then according to look-up table or the corresponding control signal of vector synthesis output, signal is through overpower
The magnet exciting coil 4 for entering respective direction of the present invention after amplifier amplification as exciting current generates corresponding magnetic field and and permanent magnetism
The magnetic field interaction that body 6 generates, to which the pipeline vibration of the respective direction controlled needs controls.
It is the configuration of the present invention is simple, easy to use, act power and reaction force and right using magnet exciting coil, permanent magnet
Pipeline vibration is controlled, not only can be real by the control to assigned direction magnet exciting coil exciting current size and direction
Now to the control of this direction vibration, and the control to other direction pipeline vibrations can be realized according to vector superposed principle, it should
It is compact-sized simple, easy to produce and installation.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
It is required that without prejudice to the basic structure of the present invention, the present invention can make any type of modification.
