针对钟形振子式角速率陀螺的振子振动特性和敏感机理进行研究,得出了一种BVG信号检测方法.采用三维Ritz方法,建立了理想条件下钟形振子中固体波动的动力学模型;利用相似系统的分析方法,推导出了钟形振子的等效动力学模型.在此基础上,研究振子环形唇缘的振动特性,分析信号产生机理,提出了利用电容传感器和压电传感器的多传感器融合的信号检测方法,并从理论上验证了该方法的合理性.对BVG的系统设计具有一定的借鉴意义.
Aiming at the vibrator vibration characteristics and the sensitive mechanism of the bell-shaped gyroscope angular rate gyroscope, a BVG signal detection method is obtained. The three-dimensional Ritz method is used to establish the dynamic model of the solid fluctuation in the bell oscillator under the ideal conditions. The equivalent dynamics model of the bell-shaped vibrator is deduced.The vibration characteristics of the ring-shaped lip of the vibrator are studied and the signal generation mechanism is analyzed.The multi-sensor Fusion signal detection method, and verify the rationality of the method theoretically.It is of some reference to the system design of BVG.
