Investigation on Eigenfrequency of a Cylindrical Shell Resonator under Resonator-Top Trimming Methods
The eigenfrequency of a resonator plays a significant role in the Feature operation of a cylindrical shell vibrating gyroscope, and trimming is aimed at eliminating the frequency split that is the difference of eigenfrequency between two work modes.In this paper, the effects on eigenfrequency under resonator-top trimming methods that trim the top o
