摘　　要：通过深入研究光纤环圈瞬态传热特性,在光纤环圈瞬态SHUPE误差数学模型的基础上,结合ANSYS有限元分析软件建立了基于交叉绕法精确到各匝光纤的环圈有限元模型。根据建立的光纤环圈温度分布模型,比较了交叉绕法与四极对称绕法环圈瞬态传热性能。结果表明:在相同的温度激励条件下,采用交叉绕法光纤环圈的SHUPE残余误差较四极对称绕法降低约90%,与实际测试结果基本相符。By studying the transient temperature performance of the fiber coil, the element model of the fiber coil in cross winding was built based on the discrete mathematics model of SHUPE error in FOG. A turn-by-turn quantization Shupe bias error model was established. Based on the temperature distribution model mentioned above, the effects of the coil with the cross winding and the fiber coil with the quadrupole winding on the temperature performance of FOG are simulated under the same temperature gradient. The results show that the cross winding coil could reduce the Shupe residual errors by 90% in comparison with the spool with quadrupole winding, and this agrees with the results of the experiments.
