摘　　要：根据速率积分陀螺浮子的结构特点,提出用陀螺在+IA和-IA位置的零位电压之差与陀螺在+SA和-SA位置的零位电压之差来控制激光去重仪在浮子IA轴向和SA轴向的光照电流,使浮子达到完全静平衡状态的闭环工作平衡法;并采用减小力矩器刻度因数来提高浮子的静平衡精度.这种方法的平衡精度高于传统方法1～2个数量级,且平衡效率高、一致性好.The paper analyses mass imbalance moment influence on the drift error of rate integrating gyro and provides the solution for decrease mass imbalance moment.By using null voltage margin of IA axis and null voltage margin of SA axis controls illumination current of laser apparatus for reduce mass imbalance moment,in order to make mass imbalance moment tend to null.A method used to decrease moment calibration coefficient increases precision of floater static balance.The solutions to decrease mass imbalance moment are called closed loop balance method(CLBM) and altering moment coefficient method(AMCM).The validity on the proposed methods has been verified and has been used to make the gyro.
