Sensitive Structure Optimization and Verification of Cantilever Beam Gyroscope

Abstract:

In order to enhance the measurement accuracy of cantilever vibration gyroscope, we modify the sensitive structure of the cantilever vibration gyroscope and develop a verifiable method. Firstly, analyzing the cause of influencing the measuring accuracy and the piezoelectric plate coupling structure of the original cantilever vibration gyroscope, we propose a new piezoelectric plate coupling structure. Secondly, in order to prove engineering feasibility of new structure, we use ANSYS software to simulate the new structure with 50, 60, 100 mm cantilevers. Simulation and experiments show that the average sensitivity of the new structure gyroscope increases by 8.64%. According to these results, we can conclude that the improved cantilever vibration gyroscope can be used in engineering application.
