Research on the Resonator of Bell Vibratory Gyro Under Axial Impact

摘要：

　　This work presents the analysis,simulation of a novel conical resonator.The resonator is the core component of a vibratory gyroscope,and the main performance of the gyro is directly influenced by its characteristics.A truncated conical metallic shell is chosen as the resonator of a novel vibratory gyroscope called Bell Vibratory Gyroscope (BVG).The shell is millimeter-scale and glued with eight piezoelectric elements.In order to investigate character of the resonator under high axial impact loading,an impact dynamic model is established using Finite Element Method.A 20,000g permanent axial impact loading is applied on the resonator.The results show that the max Von Mises stress of the resonator is much smaller than the yield strength of the material which means the plastic deformation of the resonator will not occur.Experiment is carried out to verify the effectiveness of Finite Element Method.
