Abstract
This paper presents an optimal structural design of dither mechanism in dithered ring laser gyroscope (DRLG) using finite element analysis (FEA). We establish an approximate theoretical model of the dithering mechanism to calculate resonant frequency and adopt the modal analysis and dynamics analysis to search the optimal solution. The validity and efficiency of the FEA are conformed by comparing with the sinusoidal and random vibration experimental results. An optimal dither mechanism is fabricated and measured experimentally. The results demonstrate the good vibration-isolated performance for the optimal design.
