COMPUTER MODELLING OF A PIEZOELECTRIC ANGULAR RATE SENSOR
Abstract
The paper presents the finite element (FE) modelling of operation of a rotational motion sensor that uses a balanced oscillator (tuning fork) to sense the angular rate. The 3D FE model has been employed to examining the sensor’s modal properties. The sensitivity functions have been obtained for adjusting the geometric parameters of the quartz element in order to achieve the desired values of natural frequencies. The performance of computations during the dynamic analysis has been enhanced by introducing a dynamically reduced model based on truncation of dynamic contributions of higher modes of the vibrating structure.<br /> Results are presented in terms of sensor performance characteristics for various design parameters and modes of operation. The modelling assumptions adopted are tested experimentally on the vibrating quartz resonator.
