谐振式陀螺的电路模拟及应用

The output signal of resonant gyroscope shows the characteristics of amplitude and frequency modulation on account of the action of Coriolis force, which makes it difficult to explore the characteristics of gyroscope. Based on the dynamic characteristic equation of the resonant gyro and considering the hard spring nonlinearity, the equivalent circuit of the resonant gyroscope is built by Multisim to simulate its working state. The output signal waveforms of the resonant gyroscope at different angular velocities are intuitively displayed, which can be used to analyze the dynamic characteristics of the gyroscope. Finally, this method is used to analyze the influence of gyro size parameters on its dynamic characteristics. The circuit simulation method of resonant gyroscope can be used in sensor-related courses in classroom teaching to analyze the characteristics of gyroscope, and also can be used in experimental teaching demonstration, which helps to improve students' scientific research practice ability.
