Practical structure design of cylindrical shell as an angular velocity sensor

A cylindrical shell resonator is a sensing component of the resonant angular velocity sensor. And how to fix and package the above resonator is of significant actual value. On the basis of the analyses of the practical vibration feature of the resonator, this paper studies the actual supported structure of the cylindrical shell in detail by using the finite element method, and provides some related results, that the vibration of the shell was affected by the supported rod. Furthermore, an important result that the Ψ-type resonator is the best structure was given, based on reducing the disturbance which is induced by bending vibration of the supported rod. The results obtained here are of actual engineering value for developing the resonant angular velocity sensor.
