基于浮子运动的三浮陀螺仪工作温度标定方法

Calibration method for working temperature of three-floated gyroscope based on float motion

针对三浮陀螺仪工业生产过程中,工作温度标定方法精度低、耗时长的问题,提出了一种以"浮子运动趋势拐点"作为判据的工作温度标定方法。首先对三浮陀螺仪磁悬浮标定温度进行可行性分析,然后建立陀螺仪浮子受力模型以归纳浮子运动规律,借助磁悬浮控制系统提供的浮子位置信息提出本方法。试验结果表明,该方法工作温度标定精度优于±0.02℃,较现行的"最小加力法"提高15倍以上,平均耗时缩短一半。

Aiming at the problem of low accuracy and time consuming in the calibration of the working temperature of the three-floated gyroscope in the industrial production process, a working temperature calibration method based on float trend inflection is proposed. Firstly, a mechanical model is built to analyze the motion law of the gyro floater, and the feasibilities of each temperature selection approach based on magnetic suspension are analyzed. In the light of position information of the floater, the working temperature calibration method is proposed. According to the experimental results, the calibration accuracy of the working temperature is better than ±0.02℃, which is over 15 times higher than that of the currently used minimum force method. Moreover, the temperature calibration process can be completed in less than half of the time it usually takes.
