Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the present invention includes but are not limited to following implementations
Example.
The present invention utilizes gyroscope measurement angle of rudder reflection.Angle of rudder reflection tester is function-differentiated mainly by data acquisition process mould
Block and industrial personal computer etc. form, and functional block diagram is shown in Fig. 1, are distinguished from structure composition mainly by gyroscope, fixture, communication cable and industry control
Machine etc. forms, and sees Fig. 2.Their relation and effect are illustrated respectively by function and structure composition.
From function composition, the present invention intends selecting silicon micromechanical vibratory gyroscope, which overcomes conventional rotor gyro and is answering
Limitation in, has the characteristics that structure of whole solid state, reliability height, shock resistance, small, light-weight, cost is low.The gyro
Agent structure includes four parts：Micro mechanical structure part, drive part, Detection of Weak Signals part and feedback-system section.
Wherein outer framework detection plate is connected by a pair of of flexible axle with intermediate driving wheel.During work, outer framework and wheel are in electrostatic torque
Under effect, horizontal angular oscillation is done along two axis, forms the driven-mode of gyroscope.At this time, when having turning rate input along X-axis, outside
Frame does angular oscillation under the action of coriolis force square, along X-axis, and here it is the sense mode of system.In the certain feelings of structural parameters
Under condition, its Oscillation Amplitude is directly proportional to the input angular velocity of X-direction.The angular oscillation of outer framework causes the sensitivity below frame pole plate
The change of capacitance, by detecting the variable quantity of sensitization capacitance, can obtain input angular velocity value.
From operation principle, silicon micromechanical vibratory gyroscope is as classical gyroscope, i.e., high quite when making around drive shaft
During the gyroscope sensitive angular of vibration, it, which detects the Corioli's acceleration of each particle in quality, to be used to output shaft formation Ge Shi
Property torque, so as to produce output signal.Its essence is that each particle sensitive angular produces Corioli's acceleration.The table of Corioli's acceleration
It is up to formula：
aK=2 Ω Vr…………………………………………(1)
In formula, aKCorioli's acceleration is produced for each particle sensitive angular, and Ω is measured angular speed, VrFor particle certainly
The tangential velocity of body powered motion.When detection quality is with frequency fdMake driving vibration, i.e. X=Xa sin(2πfdWhen t),
Vr=2 π fdXa cos(2πfdt)…………………………………(2)
In once complete measurement process, work experience following four state is flowed：To be triggered, data acquisition, storage,
Data are kept and data read-out and processing.Before measurement, system is in state to be triggered, and internal power supply is only to triggering at this time
Control circuit is powered, and output current is only a few μ A, can be met to be triggered for a long time.When rudder face rotates, trigger signal arrive and
Circuit start when reaching triggering level, is acquired input signal, while in the quantized value deposit RAM for the number of accepting and believing.When
When RAM records are full, system stops gathering and cuts off most of circuit power and enter low power consumption data under logic circuit control
Hold mode.Measuring device is recycled after measurement, by industrial personal computer interface data from measuring device be read into industrial personal computer into
Row processing, with reference to parameters such as gyro bias instaility, bias repeatability, constant multiplier, temperature-compensatings, is resolved by mathematics and obtained
Rudder posture.Data results can pass through industrial personal computer real-time display and record.
From structure composition, fixture is mainly made of U-bracket, 2 pressing plates, 4 attachment screws and 4 housing screws,
Pressing plate is connected on U-bracket by 4 attachment screws, and 4 housing screws are installed on U-bracket.Pass through during fixture clamping
Turn 4 housing screws pressing plate is pressed on rudder face and is tightened, it is firm that guarantee fixture is installed on rudder face, and position is correct.Gyro
Instrument is installed on fixture rear end, is fixed on fixture on rudder face.Communication cable one end is connected on gyroscope, other end connection
Onto industrial personal computer, industrial personal computer is used to showing and recording angle of rudder reflection data.Under normal conditions, a set of angle of rudder reflection tester includes 4
Fixture and 4 gyroscopes, industrial personal computer can show and record at the same time 4 road angle of rudder reflection measurement data.
Angle of rudder reflection tester is used to measuring and recording actual angle of rudder reflection, and is contrasted with theoretical angle of rudder reflection, calculates winged
Error of the row device in rudder face working range between its actual drift angle and theoretical drift angle, and corrected in the controls, with
Improve flight control accuracy.
As shown in figure 3, the present invention is by taking certain model aircraft as an example, it is desirable to it is actual inclined in the range of ± 30 ° to measure its rudder face
Angle, and contrasted with theoretical drift angle.Calculated through analysis, U-bracket and pressing plate use aluminum alloy materials, take into account cost and weight will
Ask, to improve useful life longevity, steel bushing is added at the position of U-bracket installation housing screw.Attachment screw uses standard component,
Do not tightened when connection U-bracket and pressing plate, ensure that press plate position is adjustable.For housing screw to make nonstandard part by oneself, head of screw is interior
There is annular knurl in hexagonal, outside, conveniently tightens.Gyroscope is connected by screw with U-bracket, its communication cable is connected with industrial personal computer.
