Differential CVG shock damping capacity computer simulation results

Abstract

This work presents investigation of differential Coriolis vibratory gyroscope ability to external shock suppression. First of all pulse amplitude in voltage caused by external mechanical shock of 100 g is estimated for the two sensor designs. Then, using differential CVG Simulink model, output signals of two channels are analyzed. It is shown that differential CVG damps amplitude of erroneous angle rate caused by shock directed along sensing axis of no less than 3 times in comparison with non differential CVG. As to lateral shock both CVGs have equal damping capacities.
