摘要

摘要: 光纤环是光纤陀螺的核心器件，其稳定性和抗干扰能力直接影响光纤陀螺的整机性能。以光纤环的温度特性为研究对象，通过有限元分析确定光纤环中各单元点的温度梯度，以其为数据输入；以Shupe效应理论为数学模型，设计了光纤环温度特性分析软件，实现了有限元分析结果与陀螺输出（即正反两束光的相位差）两者的有机结合。根据不同的热辐射方式、有无缓冲层、不同的绕环方法以及光纤环不对称性等情况，对光纤环的温度性能进行了具体分析。

Abstract: The fiber coil is the core part of fiber-optic gyroscope, its stability and anti-interference ability directly influences the whole function of fiber-optic gyroscope. The temperature characteristic of fiber coil was investigated and the temperature gradient of each element in coil was determined by finite element analysis. According to the Shupe effect theory, we designed the analysis software on temperature characteristic for the fiber coil, the software combined the analytical result of finite element of the fiber coil with the output of fiber-optic gyroscope, which is the phase difference between the two directions of propagation light. We analyzed the temperature characteristic for the fiber coil based on different conditions such as different hot radiation methods, with or without the buffer layer, different winding methods and the asymmetry of the fiber coil.
