The paper is devoted to investigation of a new phenomenon: Resonance oscillations in granular gases produced by a piston vibrating at one end of a closed tube. The main feature of this phenomenon, predicted by a hydrodynamic model and confirmed by computer simulations, are: (i) a column of a granular gas oscillates periodically with the frequency f/n, where f is the vibrationalfrequency, n is a positive integer number, (ii) the oscillation patterns are governed by the shock waves propagating across the column; (iii) the averaged kinetic energy per particle is proportionalto f2, and it strongly depends on the vibrational amplitude; (iv) the maximalv alue of this kinetic energy pumped by these externalvibrations is of order f2 L2, where L is the tube length.
