The Design and Simulation of Vibratory Ring Gyroscope Meiyu Meng1,a and Wendong Zhang 1 1 Key Laboratory of Instrumentation Science&Dynamic Measurement,North University of China,Ministry of Education,TaiYuan 030051,PR China amengmeiyu628@126.com Keywords: Vibratory ring gyroscope, Capacitance, Resisting vibration, Q factor Abstractor: This paper deals with design and simulation of vibratory ring gyroscope which has good performance as resisting vibration, resisting impact, small temperature drift because of the inherent symmetry of structure.
According to the information the Breaking Strength of silicon is about 1GPa,the maximum breaking strength safety factor can be used is 30% for brittle material, so that the actual maximum breaking strength of silicon may be considered about 330MPa.
