摘要
根据欧拉动力学方程建立的陀螺仪灵敏部运动方程,分析了陀螺仪光标运动的理论模型。为了采集陀螺仪实际测量中的光标运动曲线,设计了微机式陀螺仪自动测量系统。该系统可以自动完成光标采集、数据点的拟合、实时曲线描绘和测量结果计算,并可以方便地对曲线进行缩放等操作。利用傅立叶分析对采集的光标曲线进行了评价,计算了光标运动曲线的幅值谱与功率谱。说明了自动测量系统所采集的光标曲线与理论曲线相吻合,验证了测量系统在寻北研究中的可行性。
Based on the moving equation of gyroscope＇ s sensitive components which is founded by Euler dynamic equation, the theoretic moving model of gyroscope cursor is analyzed. Microcomputer automatic measuring system of gyroscope is designed which can collect the moving curve of cursor automatically,fit the data points,describe the real-time curve, compute the measuring result, magnify and reduce the curve, and so on. The amplitude spectrum and power spectrum of cursor moving curve obtained by Fourier transform show that the collected cursor curve accords with the theoretic curve in the main, which proves the feasibility of the automatic measuring system in north finding.
