An Analtical Model for Vibration Analysis of Disk Resonator Gyroscopes
2022 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL), 2022 Disk resonator gyroscopes (DRGs) utilize the circular symmetry of a set of concentric rings to realize high-performance MEMS gyroscopes. We set forth an analytical method to calculate the mode shapes of the rings and then obtain the corresponding modal mass, Coriolis mass, and stiffness. Following the Ritz method, we minimize the total potential energy
