With any attitude balance when turning.
During leveling, the 3rd flywheel module is mainly used in offsetting extraneous disturbance torque, to ensure leveling process
Effectively implement.
The operation principle of the present invention is as described below：
Three-axis air-bearing table has completed thick trim（Or due to matter that the reasons such as jet cause after three-axis air-bearing table trim
The minor variations of the heart cause three-axis air-bearing table to there is small imbalance）Afterwards, size is produced not by controlling each flywheel module
With acceleration producing different size of torque.The inclination angle of whole table top can be read by level inclination, these attitude letters
Breath acts on corresponding flywheel module to produce corresponding torque by algorithm so that the maintenance level of three-axis air-bearing table attitude is not
Become.Then whole three axles air supporting is realized by the position of counterweight in the first counterweight balance module of adjustment and the second counterweight balance module
Platform barycenter is in x, the adjustment in y faces.X is completed, after the barycenter adjustment in Y faces, then applies a given acceleration to flywheel, due to
The rotary inertia of stage body is, it is known that therefore will can obtain the theoretical value of stage body velocity of rotation.By contrasting actual value and theoretical value
Difference, we can just distinguish the direction that the counterweight of Z axis should be moved, and adjust the position of counterweight until air floating table is stable one
Individual non-horizontal position.So far, we are achieved that the automatic on-line adjustment of three-axis air-bearing table barycenter.
The structure design of counterweight balance module is as shown in figure 1, motor controls the movement of counterweight, counterweight by driving leading screw
Balance module adopts leading screw type of drive, and by leading screw the movable of counterweight is rotarily driven, and wherein slide block base plays solid
Determine the effect of counterweight, so that the rotation of leading screw can drive counterweight to move forward and backward, motor is connected drive by decelerator with leading screw
Dynamic leading screw is rotated.Counterweight balance module is arranged on the horizontal plane of three-axis air-bearing table, is respectively parallel to X, and Y-axis is orthogonally located.
Flywheel module has three groups, wherein X of two groups of rotary shafts parallel to three-axis air-bearing table, Y-axis, another group of rotary shaft is put down
Row is all arranged on the horizontal plane of three-axis air-bearing table in Z axis, orthogonally located.When needing to adjust center of gravity, stop other examinations
Test, keep control of the flywheel module to three-axis air-bearing table.The control targe of its first stage is to maintain the horizontal appearance of three-axis air-bearing table
State is constant.Three-axis air-bearing table is static, if the center of rotation of three-axis air-bearing table center of gravity and three-axis air-bearing table is misaligned, three axle gas
Floating platform will incline to a direction and tremble, and flywheel module will keep the stationary posture of three-axis air-bearing table, and its rotating speed can be to same direction
Increase.During the horizontal attitude of amendment air floating table, due to center of gravity and center of rotation deviation caused by air floating table be tilted in X, Y
It is decoupling on axle.Therefore we can correct weight by the counterweight balance module that two are respectively placed in X-axis and Y-axis
The heart.The direction of rotation of flywheel and the moving direction of counterweight are all based on the attitude data that sensor is obtained.The flywheel mould of Z axis
Block is mainly used in offsetting extraneous disturbance torque, to ensure effective enforcement of leveling process.
The center of gravity for assuming air floating table is located at the positive direction of the X-axis of center of rotation, the positive direction of Y-axis.Leveling with X-axis is
Example.If at present center of gravity is located at the X-axis positive direction of center of rotation, whole stage body can be inclined to the positive direction of X-axis.In order to eliminate this
Slope trend, the acceleration that flywheel will be rotated to X-axis positive direction according to stage body rotating to same direction, and at the same time,
Counterweight will adjust center of gravity with a certain speed according to flywheel acceleration to opposite direction movement.Because center of gravity is in X positive directions
Side-play amount is reduced, therefore stage body also can reduce to the inclined trend of X positive directions, while the rotation acceleration of flywheel and counterweight
Translational speed also can reduce, and be finally reached balance.The mode of the leveling of Y-axis is therewith in the same manner.The leveling of Z axis needs to set up in X,
On the basis of Y-axis leveling.Work as X, after Y-axis leveling, stage body can on horizontal level remains stationary.Now to flywheel one give
Fixed acceleration, due to stage body inertia, it is known that therefore stage body can also produce a specific acceleration, and depart from horizontality.
Now, if barycenter is higher than center of rotation, the inclination that can produce a torque to make stage body aggravates.The now sensor on table top
Will detect that bigger an angular velocity and angular acceleration.Now flywheel will export corresponding power according to the angular acceleration of stage body
Square, controls stage body and stablizes in the state of a non-horizontal with this, and adjusts the counterweight mechanism of Z axis to -Z direction, reduces matter
Skew of the heart in +Z direction.If barycenter is less than center of rotation, the slope trend that a torque reduces stage body can be produced.Now pass
Sensor will detect that the angular velocity and angular acceleration less than theoretical value.Now flywheel will be exported according to the angular acceleration of stage body
Corresponding torque, controls stage body and stablizes in the state of a non-horizontal with this, and adjusts the weight machine of Z axis to +Z direction
Structure, reduces skew of the barycenter in -Z direction.Repeat above step, finally, stage body can flywheel module stalling or at the uniform velocity
A non-horizontal position is still in the case of rotation.So far, adjustment of the air floating table barycenter on three axles is completed.
