Description
Technical field
The utility model relates to a kind of despin mechanism, especially a kind of racemization inertia combination device.
Background technology
The racemization inertia combination device of existing High Rotation Speed mainly applies to rotating missile, for rotary missile, because guided missile is around its longitudinal axis High Rotation Speed, based on the low-frequency filter characteristics of body, make it possible to only control the pitching of guided missile and the spatial movement of driftage both direction by a control channel simultaneously, its Control system architecture is simple, be conducive to improving guided missile and overcome such as thrust eccentric, start to control a distribution, non-uniform mass, the interference performances such as random fitful wind, be widely used in range nearer, the antitank missile that equipment amount is larger, portable air defense missile, ship to air missile, gun launched missile, terminal guidance bullet, KEM etc.
Racemization inertia combination device for High Rotation Speed realizes the measurement in its High Rotation Speed direction at present mainly through MEMS gyro or optical fibre gyro, the volume of its advantage of MEMS gyro measurement scheme is little, and cost is low, and its major defect is low precision; Its advantage of optical fibre gyro scheme is that precision is relatively high, but its volume is large, cost is high.
Utility model content
The racemization inertia combination device that the utility model provides a kind of low cost, volume is little, precision is high.
Realize the racemization inertia combination device of the utility model object, comprise racemization instrument, upper cover is provided with above described racemization instrument, below is provided with lower cover, be respectively equipped with Y/Z directional acceleration meter and switching power circuit plate between described racemization instrument and upper cover, described Y/Z directional acceleration meter is positioned at the axle center place of racemization instrument; X-direction accelerometer and control circuit board is respectively equipped with between described racemization instrument and lower cover; Described X-direction accelerometer is positioned at the side of racemization instrument, and described X-direction accelerometer is fixed with Y/Z gyroscopic compass; Described racemization instrument stretches out upper cover and lower cover one end is provided with vibroshock.
The beneficial effect of racemization inertia combination device of the present utility model is as follows:
Racemization inertia combination device of the present utility model, racemization instrument is used to replace the gyro of its High Rotation Speed X-direction, Y, Z both direction uses gyro, use three accelerometers to provide X, Y, Z tri-directional accelerations to count simultaneously, realize the measurement of High Rotation Speed, achieve the features such as small product size is little, cost is low, precision is high, X-direction range is large.
The accelerometer in Y/Z direction is arranged near system axis of rotation, ensures that X-direction accelerometer is parallel with system sense of rotation, and three accelerometers of guarantee X, Y, Z-direction have mutual orthogonality; The gyroscope in Y/Z direction arranges it is under its measuring accuracy of guarantee requires, is arranged in racemization instrument side, guarantees to have mutual orthogonality between the gyroscope of Y and Z-direction and racemization instrument direction of measurement; Improve the measuring precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of racemization inertia combination device of the present utility model.
Embodiment
As shown in Figure 1, racemization inertia combination device of the present utility model, comprise racemization instrument 1, upper cover 2 is provided with above described racemization instrument 1, below is provided with lower cover 3, be respectively equipped with Y/Z directional acceleration meter 4 and switching power circuit plate 5 between described racemization instrument 1 and upper cover 2, described Y/Z directional acceleration meter 4 is positioned at the axle center place of racemization instrument 1; X-direction accelerometer 7 and control circuit board 6 is respectively equipped with between described racemization instrument 1 and lower cover 3; Described X-direction accelerometer 7 is positioned at the side of racemization instrument 1, and described X-direction accelerometer 7 is fixed with Y/Z gyroscopic compass; Described racemization instrument 1 stretches out upper cover 2 and lower cover 3 one end is provided with vibroshock 8.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineering technical personnel in this area make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
