Design and Simulation of a DETF for Use in a Resonant Gyroscope

The principle of operation of double-ended resonant tuning forks (DETF) is described in this paper. A new kind of DETF used in the resonant gyroscope is proposed. Considering the feasibility of fabrication, the dimensions are optimized. The variation of the natural frequency against the force applied to one end of the DETF is discussed. The relation between the driving modal frequency of resonant gyroscope and the driving modal frequency of DETF is analyzed.
