Damping Tuning in the Disk Resonator Gyroscope Based on the Resistance Heat Dissipation

This paper presents a damping tuning method for the resonator with parallel plate capacitors for driving, sensing and tuning. This damping tuning method bases on the resistance heat dissipation and is easy to realize. The damping tuning theories are derived firstly, in which we find that the damping tuning and stiffness tuning in the resonator with parallel plate capacitors are coupled with each other. This phenomenon makes the damping tuning become more complex but on the other side it can be used for synchronous tuning of the damping and stiffness. To verify the theories, a honey-comb like disk resonator which is a typical resonator with parallel plate capacitors is designed and tested. The testing results demonstrate the damping tuning theories derived in this paper and this method can be further used on the damping tuning in other resonators.
