The Theory Based on the Displacement of Mass of MEMS Gyroscope Used in Spinning Projectiles Analysis and Simulation

Abstract:

The MEMS gyroscope used in Spinning Projectiles is a single-chip and axis gyroscope drive by high-speed rotary of Spinning Projectiles. To analysis this theory, a corresponding mathematical module was established based on the structural principle of the gyroscope and the Kinetic parameters included in the mathematical module was analyzed and calculation. By calculation, the paper had drawn the curve between the displacement of mass and the input angular velocity. By using ANSYS software the vibration mode and harmonic response have been done, after comparing the results of imitation and calculation, it is found that the difference is little, so the theory based on the displacement of mass is correct.
