Structural Analysis of Disk Resonance Gyroscope

Structural Analysis of Disk Resonance Gyroscope

In this paper, we present two design methods to improve the performance of disk resonator gyroscope (DRG), including decreasing the frequency split and increasing the quality factor (Q). The structure parameters, which can affect the frequency split and Q value were concluded with the help of the FE...
