RADIAL ELECTROELASTIC NONSTATIONARY VIBRATION OF A HOLLOW PIEZOCERAMIC CYLINDER SUBJECT TO ELECTRIC EXCITATION

摘要

The paper studies the radial nonstationary vibration of a piezoceramic cylinder polarized throughout the thickness and subjected to a dynamic electric load. A numerical algorithm for solving an initial-boundary-value problem using mesh-based approximations and difference schemes is developed. The dynamic electroelastic state of the cylinder subjected to a constant potential difference applied instantaneously is analyzed.
