摘要

针对光纤陀螺惯性导航装置启动过程中非稳态温度场对光纤环性能的影响,构建了以四极对称绕法为基础的热漂移误差模型,理论分析了缓变温度条件下Shupe效应和热应力对零偏误差的影响,讨论了光纤环每层匝数与热效应误差的关系。提出了一种简单高效的光纤环温度性能评价试验方法,试验证明该方法具有较好的评估准确性。

Abstract

For the effect of unsteady temperature field on the performance of fiber coil during the startup process of fiber optic gyroscope inertial navigation device, the thermal drift error model based on the quadrupole winding is established in this paper. The influence of Shupe effect and thermal stress in the slowly varying temperature field is analyzed theoretically. The relationship between the number of turns per layer and the thermal stress in the fiber coil is discussed. A simple and efficient experimental method for temperature performance evaluation of fiber coil is proposed. The experimental results show that this method has a good accuracy.
