振动性能是体现光纤陀螺环境适应性的一项重要指标。结构谐振是引起光纤陀螺振动误
差的主要因素之一。在描述了光纤传感环圈骨架谐振对陀螺振动性能影响的试验现象的基础上，通过环圈骨架的有限元分析，以及光纤陀螺振动误差模型的推导，得出了环圈骨架谐振频率与陀螺振动输出零位漂移最大点的频率相吻合的结论(The performance of FOG under vibration conditions in quite important, which shows its environmental ruggedness. One of the main causes of vibration error in FOG is the structural resonance.Experiments were done to show the relationship between vibration error and structural resonance. The spool was analyzed in finite-element method, and the expression of vibration error was conducted.)
