| 摘 要： | 研究的目的是分析和优化光纤陀螺三轴组合的热设计方案。从光纤陀螺三轴组合内部热源出发，使用FLOTHERM软件建立了主电路板仿真模型，进行分析解算，得到了主电路板在室温条件下达到稳定状态的温度云图，并与红外热扫描结果加以分析比较，验证了所建模型的正确性。在此基础上，对光纤陀螺三轴组合温度场进行了仿真分析，发现了电路板过热和光纤环温度分布不均匀等问题，提出了改进措施，仿真结果表明，新的设计方案解决了以上问题。

| Abstract: | In order to analyse and optimize the thermal design scheme of the three-axis Fiber Optic Gyroscope,this paper first discuss the internal thermal resource of three-axis Fiber Optic Gyroscope.Then the author build the simulation model for printed circuit board,which also has been analyzed and solved more,And the PCB's steady temperature distribution under the room temperature which compared with the result obtained from the infrared thermal scanner shows the correcting of the PCB model has been achieved.On the basis of this,simulate three-axis FOG,discover the problems that contains the temperature of the circuit board is too high and the odds of the distribution of fiber ring's temperature.Finally,a new improved method has been put forward.By simulating and calculation,the new method has been proved to solve all the problems above. |
