Abstract

The thermal performance under variable temperature conditions of fiber coils with double-cylinder (D-CYL) and quadrupolar (QAD) winding methods is comparatively analyzed. Simulation by the finite element method (FEM) is done to calculate the temperature distribution and the thermal-induced phase shift errors in the fiber coils. Simulation results reveal that D-CYL fiber coil itself has fragile performance when it experiences an axially asymmetrical temperature gradient. However, the axial fragility performance could be improved when the D-CYL coil meshes with a heat-off spool. Through further simulations we find that once the D-CYL coil is provided with an axially symmetrical temperature environment, the thermal performance of fiber coils with the D-CYL winding method is better than that with the QAD winding method under the same variable temperature conditions. This valuable discovery is verified by two experiments. The D-CYL winding method is thus promising to overcome the temperature fragility of interferometric fiber optic gyroscopes (IFOGs).

摘要

对采用双圆柱（D-CYL）缠绕方法和四极（QAD）缠绕方法的光纤线圈在变温条件下的热性能进行了对比分析。通过有限元方法（FEM）进行模拟，以计算光纤线圈中的温度分布和热致相移误差。模拟结果表明，D-CYL光纤线圈在经历轴向不对称温度梯度时本身具有脆弱的性能。然而，当D-CYL线圈与热隔离卷轴啮合时，其轴向脆弱性能可以得到改善。通过进一步模拟我们发现，一旦D-CYL线圈具有轴向对称的温度环境，在相同的变温条件下，采用D-CYL缠绕方法的光纤线圈的热性能优于采用QAD缠绕方法的光纤线圈。这一有价值的发现通过两个实验得到了验证。因此，D-CYL缠绕方法有望克服干涉式光纤陀螺仪（IFOG）的温度脆弱性。
