对称分布的三轴谐振陀螺仪的设计、分析与仿真
Design,Analysis and Simulation of the Symmetrical Distribution of Three Axis Resonant Gyroscope
摘要
Abstract
A square symmetrical tri-axis gyroscope structure was proposed to realize the monolithic integrated three-axis gyroscope. Firstly,the idea of design and working principle of the gyroscope was introduced,while the dynamic model with its dynamic equation was given. Then,the structure static analysis and modal analysis was simulated by using the Ansys software . The simulation results shows that the maximum stress under the applied load of 100 GHZ under load is 1.942 MPa,while the Natural frequencies of each mode are 57.345 kHz,57.382 kHz and 57.395 kHz,which means that the matching performance between modal is good. The simulation for this gyroscope structure demonstrate that the mode matching performance and resistance to overload and meet the design require⁃ments for the tri-axis gyroscope.关键词
