Abstract
This paper presents the design and simulation of a microelectromechanical gyroscope that simultaneously determines two components of angular velocity. In this device, the silicon sensor is started by an electrostatic actuator to perform a linear harmonic motion at a controlled speed. The movable masses of the sensor move in two directions, orthogonal to the primary vibrations of the sensor under the action of Coriolis forces. This paper considers how temperature influences eigenfrequencies and informative vibrational magnitudes of the micromechanical angular velocity sensor. The parameters that have the greatest impact on the sensor output behavior are determined by a finite-element analysis method. Techniques to stabilize vibration eigenfrequencies of the sensing element are suggested.
