摘要
通过深入分析光纤陀螺敏感环的特点,提出了一种工艺简单的双柱型(D-CYL)绕法。通过有限元方法仿真分析了双柱型绕法环圈瞬态传热性能,对比分析了在相同变温条件下双柱型绕法与交叉绕法对陀螺性能的影响。结果表明,在对称的温度环境下,双柱型绕法在抑制陀螺温度漂移方面的效果与交叉绕法相当,两者漂移误差均低于0.01 (°)/h,与理论分析相符。
Abstract
By deeply analyzing the characteristics of interferometric fiber optic gyroscope sensitive ring, a double-cylinder (D-CYL) winding method with a simple process is proposed. Simulation by finite element method is conducted to analyze the transient heat transfer performance of the D-CYL winding coils and a comparative analysis is made to find out the different effects of D-CYL and cross winding methods on fiber optic gyroscope under the same variable temperature. The results show that, under a symmetry temperature environment, the D-CYL winding method shows almost the same performance in suppressing phase drift error as the cross winding method, and both errors are within 0.01 (°)/h, which is consistent with that from the theoretical analysis.
