Abstract
A novel piezoelectric rotational speed meter which is within the family of solid-state wave gyroscope based on direct and inverse piezoelectric effect is proposed in the paper. The hard core of the speed meter is a vibratory ring with circular inner surface and octagonal outer surface. First, the paper presents the principle introduction and structure design of the rotational speed meter. Second, simulation results and mode test results show appropriate working modal frequency and modal shape. We found that the working frequencies of active and sense mode are nearly equal. In addition, coriolis test are done to validate the working principle. Finally, the data from the experiment are analyzed to obtain the equation between output signals and angular velocity. We conclude two equations which can be used to work out the angular velocity input and the scale factors of the equations are 16.4 mV/min/r and the correlation coefficient is 0.998 and 0.995 respectively. These results are more accurate when the angular velocities range from 5 to 700 RPM.
