Dynamic Analysis for Bracket of FOG

Fiber Optical Gyroscope (FOG) is becoming affordable for many applications such as vehicle navigation and stabilization. Operating under the circumstance of which, vibration can’t be ignored. This paper researched into the characteristic of vibration of structure of FOG. Base on the model analysis using ANSYS (finite element analysis software), we did dynamic analysis for bracket of FOG. On the model analysis, we got the frequencies and model shapes of bracket. On the harmonic response analysis, we got the curves of frequency response. We analyse the frequencies and model shapes of bracket. At last, we brought forward the methods to optimize the framework design of FOG.
