摘要

A novel tuning fork micromachined gyroscope

based on slide-film damping

is presented. The electrostatic driving gyroscope consists of two driving masses each of which supports one sensitive mass. The angular rate is sensed by the differential capacitances consisted of movable bar electrodes and fixed bar electrodes located on the glass wafer. The gyroscope can operate at atmospheric pressure with slide film damping in the driving and sensing directions

eliminate vacuum packaging and restrain cross-axis acceleration signal. The results of design and simulation show that the driving and sensing mode frequencies are 3 106 Hz and 3 175 Hz

respectively

and the

-values in driving and sensitive modes are 1 721 and 1 450 respectively. The design resolution is 0.025°/s.
