Research of a Novel Combined Metal-Fused Silica Resonator for Cylinder Shell Vibrating Gyroscopes


Article Preview

A novel combined metal-fused silica resonator for the cylinder vibrating gyroscope is proposed in this paper. The cylinder wall of the resonator is made of fused silica, while the bottom is made of metal, and then the two parts are connected by strong glue. With this method, the manufacturing difficulty of the fused silica resonator can be reduced significantly and the performance can be retained without remarkable degeneration. In this paper, the novel metal-fused silica resonator is analyzed, including the structural optimization design and fabrication, testing of the stability of the resonance frequency and the Q factor. The preliminary experimental results show that the low-cost combined metal-fused silica resonator has potential good performance to achieve high accuracy in a cylinder shell vibrating gyroscope.
