Description
Technical field
The utility model relates to non-ferrous metals processing field more particularly to a kind of Ni32Co4Nb alloy dithering-wheels.
Background technique
Dithering-wheel is a kind of device applied to rlg sensor field, is mainly used for carrying out laser gyro inclined
Frequently.The principle of the offset frequency is: due to backscattering of laser gyro reflecting mirror etc., so that there is solid for laser gyro
The area You Suo phenomenon, and lead to gyro no signal output at the low rotational speed, it is therefore necessary to lock area is reduced to top by Frequency-Biasing Technique
The influence of spiral shell, to improve the precision of rlg sensor.
It is directed to time, researcher develops a variety of Frequency-Biasing Techniques, including mechanical shaking offset frequency, rate biased, magnetic mirror are inclined
Frequently, the schemes such as Zeeman offset frequency, four-frequency differential, mirror jitter offset frequency.But since laser gyro is actually (right with umber of pulse
Ying Yu is in corner) rather than using instantaneous beat frequency (corresponding to revolving speed) as output, as long as so positive and negative half period offset frequency amount clock synchronization
Between integral i.e. umber of pulse is equal would not cause too big error, the high degree of symmetry of not overcritical waveform and amplitude.Therefore, machine
The alternation Dithered of tool just has having an enormous advantage.
After alternation Dithered is added, gyro can only be in blocking, remaining major part in a short period of time
Except time service Yu Suoqu.In this way, even if input angular velocity very little, since total time of the gyro in lock area is very short, by closing
Lock bring error also greatly reduces.The system of complete mechanical shaking laser gyro includes goggles, light-combining prism, yin
Pole, anode, spherical mirror and shaker mechanism.Shaker mechanism therein includes dithering-wheel, and fits in the shake wheel spoke
On PZT (lead titanate piezoelectric ceramics) piece, for by itself instigate so that dithering-wheel drive cavity come back rotation, thus
The mechanical shaking offset frequency of a positive and negative alternation is added to gyro.
Due to needing strict control shaker mechanism positive and negative half period offset frequency amount to the integral of time, for using two-way spoke
For the dithering-wheel of structure design, central axis is hanging in the operating condition, and symmetrical eight flat springs piece is set around central axis
It is placed on the outside of the spoke of dithering-wheel, wherein four flat spring pieces are connected with gyroscope cavity, and the outer end of other four flat springs piece and base
Seat is connected, along with PZT piece passes through epoxy glue gluing in the spring leaf being connected with pedestal.Therefore for the size Control of dithering-wheel
It needs to guarantee enough accurately, to guarantee that spring leaf does not occur with being mounted under the dithering-wheel working condition for PZT piece
Deviation.
And existing dithering-wheel can cross reduction as the temperature rises, and its dimensional structure is made to change, cause to tremble
Mechanical shaking offset frequency caused by motivation structure is undesirable so that the lock Qu Zengjia of rlg sensor and can not normal work
Make.
