摘要
介绍了高精度光纤陀螺零位误差的形成原理,并就温度和磁场对高精度光纤陀螺零位误差的影响进行了详细的理论分析。仿真结果表明:由于温度引起的零偏峰值漂移为0.06°/h。最后,对交变温度场和径向静磁场交联作用下的情况建立了理论模型并进行了实验研究,实验结果表明:在径向磁场和不同温度作用下,光纤陀螺由于交联耦合效应产生的径向磁场灵敏度变化,即交联耦合度<1%,这和理论模型具有较高的一致性。
The formation principle of zero error on high precision fiber-optic gyro was introduced,and the impact of temperature and magnetic field on the zero error of high precision fiber-optic gyro was analyzed in detail.The simulation results show that the zero-bias peak value drift caused by temperature is 0.06°/h.Finally,the theoretical model and experimental research were carried out under the cross-linking condition of alternating temperature field and radial static magnetic field.The experimental results show that under the action of radial magnetic field and temperature,the maximum drift value of the fiber-optic gyro generated by the cross-linking coupling effect is about 1%order of the sensitivity of the radial magnetic field,which is consistent with the theoretical model.
