In this paper we deal with the simulation of multiaxial angular velocity detection for a vibratory gyrosensor using a diaphragm vibrator with an additional inertia. The diaphragm vibrator is constructed as a triple-mode resonator, and the inertia has vibrational motions in three degrees of freedom. In this vibrator, two orthogonal forces are used to drive it, and therefore, the trajectory of the inertia motion forms a circle. Under this condition, the three components of the applied angular velocities individually change the trajectory. Therefore, we can determine these three components of the angular velocities from their trajectory change. In the first part of this paper, we describe the theoretical operation principle of the gyrosensor, and the second part contains the simulation of its vibrational characteristics using the finite-element method, including the Coriolis force effect. The results indicate that the multiaxial angular velocities can be detected.
