The damping asymmetry of cylindrical resonators is one of the major sources which result in the gyroscope’s drift. In this paper, a new approach for trimming the damping asymmetry of cylindrical resonators is proposed. The damping asymmetry trimming model is established to analyze the additional damping’s influences. Furthermore, piezoelectric electrodes’ effects on the cylindrical resonator’s damping characteristic are figured out through the finite element simulation. The procedures of this trimming method are also summarized based on theoretical analysis. At last, these theoretical analysis and simulation results are utilized to compensate the damping asymmetry of cylindrical resonators and the procedures of this trimming method are also summarized. Experiments are also implemented to verify this trimming method. |
