Piezo electric gyro free#
Free and forced vibration solutions are obtained showing high voltage sensitivity. The equations are employed in the analysis of the bimorph gyroscope. The present research is concerned with the free vibrations and energy transfer of a vibrating gyroscope, which is composed of a flexible beam with surrounded piezoelectric films in a rotating space. The gyro sensor is achieved if two perpendicular vibration modes can be driven and detected in.
For the analysis of the gyroscope, one-dimensional equations of beam piezoelectric bimorphs are derived from the thr ee-dimensional equations of linear piezoelectricity. Thepiezoelectric effectis used as a drive/detection method. Fax: +1 4 E-mail: Ībstract: The mechanism of piezoelectric transformers for producing high voltage is incorporated into a ceramic beam bimorph piezoelectric gyroscope for generating high voltage sensing signal. In this paper, the resonance characteristics of a rectangular lead.
Obtaining working resonant mode with high quality is key to improve the performance of piezoelectric resonators. Piezoelectric resonators usually work in a special resonant mode. bĪffiliations: Department of Engineering Mechanics, University of Nebraska, Lincoln, NE 68588, USA | Department of Mechanical Engineering, University of California, Riverside, CA 92521, USAĬorresponding author. Piezoelectric resonators are widely used in frequency reference devices, mass sensors, resonant sensors (such as gyros and accelerometers), etc. PROBLEM TO BE SOLVED: To provide a piezoelectric vibration gyro of which processes and working jigs are reduced, mass prodution adaptability is good, and manufacturing is easy, by using piezoelectric vibrators which are made of materials of various propagating speed and actually formed into the same shape.
