摘　　要：双折射效应、Shupe效应等与温度相关的效应和部分结构较脆弱的光学器件等因素,使某微型光纤陀螺不能在宽温度范围和高冲击环境条件下正常工作。通过有限元热仿真分析和隔冲理论计算进行结构优化设计保证某微型光纤陀螺在-45~65℃的温度范围和3 000g的半正弦冲击下正常工作。实验证明该优化设计方案在确保光纤陀螺测量精度指标的同时,大幅提高了该型号光纤陀螺的环境适应能力。Because of double refraction effect,Shupe effect and some fragile optic component,a micro FOG can't work in a wide temperature range and high impact test environment.A new structure optimization design has been proposed by finite element thermal analysis and shock isolation theory to make sure the micro FOG can work effectively under range of-45~65 ℃ and half sine impact test.The experiment results prove that this structure optimization method can guarantee the accuracy of FOG and its environmental adaptability has been greatly improved.
