Description
Technical field
The present invention relates to the preparation field of electromagnetic locking device electromagnet, is performed more particularly to a kind of magnetic suspension inertia
The design method of the repeatable electromagnetic locking device electromagnet of mechanism.
Background technology
Magnetically levitated flywheel and magnetic suspension control torque gyroscope are supported using magnetic suspension bearing, eliminate what mechanical bearing was brought
Fretting wear, vibration is reduced, improve output torque and control moment precision, be the preferable inertia actuator of spacecraft.
Because transmitting powered phase has fierce vibration and impact, to prevent from occurring between the magnetic suspension stator and rotor of non-contact suspension bearing
Fierceness is collided and impacts and damage, and magnetic suspension inertia actuator must use locking device, and locking confining guard is carried out to it.
Launch powered phase, locked flywheel by locking device；After entering the orbit, also need to release the original locking relation of rotor, make at rotor
It is easy to suspend in free state.
According to locking and unblock number, locking device can be divided into disposable locking device and repeatable locking device.At present
Used disposable locking device mainly has based on carbon fibre composite and aircraft cable locking device, wedge-cone
Shape bearing locking device, screw-and-nut locking device.Three of the above scheme is unlocked using priming system, and reliability is high, but
It is used only once, is not easy to ground environment test adjustment.Because the positive sample product of magnetic suspension inertia actuator need to lead to before transmitting
It is (swept-sine vibration, random vibration, mechanical shock, centrifugal acceleration, high/low temperature, thermal cycle, old to cross a series of environmental test
Refining etc.), often it need to lock and unlock.In addition when flywheel become rail work, it is also desirable to which it is locked and unlocked repeatedly.Mesh
Repeatable locking device used in preceding mainly has based on motor-shell fragment-steel wire rope locking device, based on motor-lever locking
Device, based on motor-conical surface locking closure locking device and electromagnetic locking device.Base disclosed in number of patent application 200910093150.0
In motor-shell fragment-steel wire rope locking device, by the use of shell fragment as mechanism is upheld, by the use of steel wire rope as tightening system, pass through electricity
Machine forward and backward, drive tightening system to uphold mechanism and collapse or unclamp, so as to hold or discharge flywheel rotor tightly, realize flywheel
Repeat locking and unblock.Because shell fragment rigidity is relatively low, cause the locking rigidity of locking device relatively low, cause to launch powered phase flywheel
Vibration displacement between stator and rotor is bigger than normal.In addition, shell fragment along flywheel rotor radial circumference be distributed, add flywheel machine volume and
Weight.Number of patent application 201010117577.2 is disclosed to be based on motor-lever lock device, utilizes motor forward and backward, driving
Flywheel rotor is locked or discharged by leverage.Using lever boosting mechanism, coupling mechanism force and locking rigidity are improved.But Lever machine
Structure size is larger, and is positioned over below flywheel rotor, adds the axial dimension of flywheel complete machine, result in the increasing of main screw lift
Add.Number of patent application 201210338347.8 is disclosed to be based on motor-conical surface locking closure locking device, by motor forward and backward, drives
Mantle face locking closure compresses or unclamped flywheel rotor, realizes the repetition locking and unblock of flywheel.Conical surface locking closure is positioned over stator core
On the inside of Axial and radial, flywheel volume and weight is reduced, but the constraint area of the conical surface locking closure conical surface is smaller, and locking constraint rigidity is inclined
It is low, cause in vibration processes that vibration displacement is larger between stator and rotor.Electromagnetic locking disclosed in number of patent application 200810119968.0
Device, by controlling the electromagnetism magnetic field of electromagnet and permanent magnetic field is forward and reverse is superimposed, the suction of sucker is increasedd or decreased, is realized
The repetition locking and unblock of flywheel.During work, three to four electromagnetic locking devices are placed typically on the inside of flywheel rotor, will not be led
The increase of flywheel machine volume weight is caused, while improves locking rigidity.
Critical component of the electromagnet as electromagnetic locking device, it locks startup power and unblock residual force determines and performs lock
Tight and execution unblock reliability, it is locked confining force and unlocks confining force and determines holding locking and keep the reliable of unblock
Property, so needing to carry out detailed design to it.Existing Electromagnetic Design method is each to electromagnet using FInite Element or Magnetic Circuit Method
Item index is individually designed.The simple efficiency high of this method, but its design result is often less reasonable, typically cannot get optimal result.
