摘　　要：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。Based on the analysis of the spindle rotary error of centrifuge with counter-rotating platform,the influence of the spindle rotary error on the test accuracy of PIGA(pendulous integrating gyro accelerometer) was studied to improve the test accuracy.According to the second-order coefficient regression model and multiple coefficients regression model for PIGA test on centrifuge,the mathematic expression of the effects of the centrifuge spindle rotary error on PIGA second-order coefficient estimator and several estimators including PIGA third-order coefficient estimator were derived,and used for error compensations.
