Abstract

The vibration stability of FOG (fiber-optic gyroscope) is one of the most important factors in design. With the theories of vibration analysis and finite element analysis (FEA), the natural frequency, vibration modes and dynamic analysis were calculated and simulated by ANSYS5.7. The FOG's vibration modes, within 0-5 kHz, were measured with Polytec-PS200 vibration meter. Compared with the FOG's output characteristic under the vibration, the relation had been found between components' vibration characteristic and the vibration stability of FOG. An optimization structure of FOG was provided based on the research results. It's null shift output was minimized about 65%.
