The Theory and Application about Dynamic Tuned Gyroscope

The dynamic tuned gyroscope refers to a gyroscope which is supported by two pairs of orthogonal torsion bars and a flexible joint.By using the negative elastic moment generated by the dynamic effect, the positive elastic moment of the elastic torsion rod is offset, and the rotor is in the free rotor state with no torque, and the precision of the gyroscope will be improved.

At present, the dynamic tuned gyroscope has been used in water surface, land straggling, fast north finder and TV antenna tracker, and it is widely used in the space shuttle inertial navigation system and the attitude system of high dynamic carrier.The dynamic tuned gyroscope can be used in the ground, sea, aviation, space transportation carrier’s Jet-type and platform attitude system.

In the field of drilling, the application of inertial device than flying field, higher request on the technology, stronger on product adaptability, because of its working conditions, high temperature, the temperature adaptation and life are very demanding, specially designed for well logging under the condition of the development of higher precision of dynamically tuned gyroscope, overcame the technical difficulties, and its working temperature is 100 ℃.
