| Abstract: | The 3D finite element modal of dithering system of laser gyroscope is constructed in this paper, and the modal analysis for its vibration characteristic is performed. The modal test for the system is made, and the two results obtained above are compared. The accordance of the two results reveals that the finite element modal constructed in this paper is rational, and the analysis result is reliable. It is very helpful for improving the design of the system. |
