石英音叉陀螺仪是一种典型的振动陀螺仪,其在不同载体振动环境中的零位控制技术对制导武器弹体姿态的准确测量非常重要。由于石英音叉陀螺仪本身存在驱动频率、谐振频率和频差等基本振动陀螺仪物理参数,其与载体的基频和倍频可能出现重合进而相互干扰。分析了石英音叉驱动频率、检测频率,载体基频和倍频的相互影响及其在陀螺零位输出状态上的影响形式。针对不同载体频率,设计了石英音叉陀螺仪驱动频率的优化方案并进行振动试验验证,试验结果表明在载体基频180 Hz±5 Hz条件下,石英音叉陀螺仪的驱动频率在11 kHz左右的选取方式能够有效控制陀螺零位输出状态。

Quartz gyroscope is a typical vibrating gyroscope. Its zero position control technology indifferent carrier vibration environment is very important for the accurate measurement of guided weapon’s attitude. Because the quartz gyroscope has some basic physical parameters, such as driving frequency, resonance frequency and frequency difference, it is inevitable that the fundamental frequency and octave frequency of the carrier may overlap and interfere with each other. This paper analyzes the interaction of driving frequency, detection frequency, carrier fundamental frequency and octave frequency as well as their influence forms on the zero position output state of the gyroscope, designs the optimization scheme of driving frequency of different carrier frequencies of the quartz gyroscope, and carriers out vibration test verification.The test results show that under the condition of carrier fundamental frequency, the driving frequency of quartz gyroscope can effectively control the output state of gyro zero position.
