摘要
Shupe误差是高精度光纤陀螺(IFOG)工程化过程中的最大瓶颈问题之一。建立一个精确到匝的光纤环有限元模型,基于此模型,并在不同温度激励下分析八极、十六极和三十二极对称绕法的温度性能。仿真结果表明:相对于八极对称绕法,采用十六极对称绕法和三十二极对称绕法的光纤陀螺能够有效抑制热致陀螺漂移,且十六极对称绕法的抑制效果最好。这对高精度IFOG的光纤环绕制方法的选择提供了指导。
The Shupe bias error is one of the biggest bottleneck problems in the engineering application of interferometric fiber optic gyroscope(IFOG).A turn-by-turn finite element model for fiber coils is established in this article.Based on this model,analyze the temperature performance of the 8 level,16 level and 32 level symmetric winding method are analyzed under different temperature excitations.The results show that compared with octupolar symmetrical winding methods,the 16-polar and 32-polar symmetrical winding methods can effectively reduce the thermally induced gyro drift,and that the 16-polar symmetrical winding methods have the best temperature performance among the three methods.This conclusion provides guidance for the selection of fiber coil winding method for high precision IFOG.
