为提高陀螺加速度计的测试精度,在分析带反转平台离心机主轴回转误差的基础上,研究了主轴回转误差对陀螺加速度计测试精度的影响。根据陀螺加速度计离心机测试的二次项系数回归模型和多系数回归模型,分别推导了离心机主轴回转误差对陀螺加速度计二次项系数测试和包括三次项系数在内的多个系数测试的辨识精度影响的数学表达式,并进行了误差补偿。
In order to improve the test accuracy of the gyro accelerometer, the influence of the spindle gyration error on the test accuracy of the gyro accelerometer was studied based on the analysis of the gyro error of the spindle with the reversing platform. According to quadratic coefficient regression model and multi-coefficient regression model of gyro-accelerometer centrifuge testing, the quadratic coefficient tests of gyroscope accelerometer and multiple coefficient tests including three-term coefficient Identify the mathematical expression of the influence of precision, and carry on the error compensation.
