摘要
利用有限单元法,对光纤陀螺在非稳态传热过程中的温度场进行数值分析,通过将仿真结果和试验结果进行对比,说明利用有限元这种方法可以对光纤陀螺的温度场进行准确的计算。另外,基于得到的光纤陀螺温度参数进行了相关的拓展计算,得到了一些定性的结论,可作为温度补偿的理论基础。
The fiber optical gyroscope was studied by finite element method under various exterior circumstances temperature.Comparing with the results yielding from simulation and experiment, temperature filed was simulated in fiber optical gyroscope by using finite element method accurately.Based on the parameters deriving from the procedure mentioned above, some further calculations were carried out to study the temperature characteristic of fiber optical gyroscope and obtain some useful results.It can be considered as the theoretical basement for temperature compensation.
