摘　　要：通过深入研究八极绕法,实现了改善光纤陀螺温度性能的目的。在光纤陀螺Shupe误差数字离散公式的基础上,建立了采用八极绕法绕制的光纤环圈的有限元模型。对基于八极绕法的光纤环圈中的Shupe误差进行了以匝为单位的量化分析。根据建立的基于八极绕法的光纤环圈温度分布模型,分析了在相同的径向温度激励下八极绕法与四极对称绕法对陀螺性能的影响。结果表明:采用八极绕法绕制的光纤环圈与采用四级对称绕法绕制的光纤环圈相比,陀螺热致速率误差减少了80%,与实验结论相符。By studying the octupole-winding method,the improvement of the fiber optic gyroscope’s（FOG’s） temperature performance was realized.The element model of the fiber coil with the octupole-winding pattern was built based on the discrete mathematics formulae of Shupe error in FOG.A turn-by-turn quantization Shupe bias error model was established in octupole-winding method.Based on the temperature distribution model mentioned above,the effects of octupole-winding coil and quadrupole-winding coil on the temperature performance of FOG were simulated under the same radial temperature gradient.The results show that the octuple-winding method could reduce the Shupe bias errors by 80% in comparison with the quadrupe-winding method,and this agrees with the results of the experiments.
