    Experimental investigation of the maximum quality factor axes temperature deviation in metallic coriolis vibratory gyroscopes resonator
    (КПІ ім. Ігоря Сікорського, 2021) Petrenko, O.; Chikovani, V.; Golovach, S.; Strokatch, G.
    A metallic cylindrical resonator is a well known base detail of the significant part of Coriolis vibratory gyroscopes (CVG) [1] including a MEMS gyro. It own parameters just after mechanical manufacture in main are determine an advisability of further utilize and the future gyroscope accuracy potential. Initial testing CVG resonators directly after their manufacture often done using the optical method [2, 3] or acoustic method [4, 5]. Unfortunately investigated manufacture quality of the resonators by using acoustic method not very well describe in scientific literature. A paper presents the results of some extension acoustic investigations of the metallic CVG resonators. This result describes the behavior of maximum quality factor (Q factor) axes and own resonant frequencies axes under stabilized temperature step influences and can be used in prediction for CVG bias minimization during it works in temperature range.
