光纤环的应力测试分析

光纤环作为光纤陀螺的主要构成部分,其内部应力变化会给陀螺精度带来不可忽视的影响。介绍了光纤应力分析仪的工作原理,并初步探讨光纤环在各种条件下的应力分布及使用光纤应力分析仪对其进行其测试的结果。通过ANSYS有限元分析光纤环支架在不同温度变化和振动前后对光纤环应力变化的影响。在此基础上,提出了陀螺结构改进方法。

Measurement and analysis about the strain of fiber opitical loop

Fiber optical gyroscope(FOG)is becoming affordable for many applications such as vehicle navigation and stabilization. Operating under the circumstance of which, strain can't be ignored. This paper introduce the principle of the optical fiber strain analyzer, and analysis the distribution and variation of optical loop's strain which vary after the variation of temperature and vibration by ANSYSAt last, we brought forward the methods to improve on the framework design of FOG
