摘要
由于在科里奥利力的作用下,谐振式陀螺的输出信号呈现调幅调频特性,为探究陀螺特性增加了难度。该文基于谐振式陀螺的动态特性方程,在考虑硬弹簧非线性情况下,利用Multisim搭建谐振式陀螺等效电路来模拟其工作状态,直观展示了输入不同角速度时谐振式陀螺的输出信号波形,进而可用来分析陀螺的动态特性。文章最后还使用该方法举例分析了陀螺尺寸参数对其动态特性的影响。谐振式陀螺电路模拟方法可用于传感器相关课程课堂教学,用于分析陀螺特性,也可用于实验教学演示,有助于提高学生的科研实践能力。
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.
