The authors describe the construction of a difference scheme to solve problems on dependent electroelastic non-stationary oscillations of a hollow piezoceramic cylinder that was preliminarily polarized along the radius. The variational-type difference scheme bases on the law of energy conservation in electromechanical systems. A stability condition is obtained for such systems. Convergence of the approximate solutions to the sufficiently smooth solution of the initial second order differential equation is proved. Numerical experiments are carried out for cylinders with different polarizations.
