Owing to the constructionrof the vibrating body and the absence of the bearings, the vibratory gyro has a number of advantages over the conventional rotating-wheel gyro, such as ruggedness, simplicity, long life, rapid response, wide range of rate measured with good linearity.
An experimental study on an outline of characteristics of vibratory gyros is reported in this paper in which the tuning-fork type gyro having a certain amount of moment of inertia is compared with the tuning-ring type gyro having the same amount of moment of inertia, for the purpose of making a general engineering application, as against inertial guidance where extreme sensitivity and stability may be required.
The results obtained are as follows :
1) As for response, the tuning-ring gyro is superior to the tuning-fork gyro.
2) Asirto linearity, the tuning-fork gyro is superior at the rate of less than 0.1 rad/s, namely at low speed, while the tuning-ring gyro is superior more than 3 radfs at high speed.
3) The tuning-fork gyro is much influenced by centrifugal force and eccentricity of the gyro's axis.
4) The resonance of the torque pick-up and vibrating mass can be obtained more easily in the case of the tuning-fork gyro.
