The model of gas oscillations under external harmonic load considering the gas relaxation properties and environment resistance force has been developed. The studies carried out using numerical analysis show that coincidence of the environment oscillation frequency with the external load oscillation frequency results in resonance, followed by the environment unlimited oscillation amplitude growth without considering its internal resistance. Resonant oscillations occurring under the environment resistance forces demonstrate the results as follows: May be the either damped oscillations in case of large resistance factor values, undamped oscillation in the process of stabilized amplitude and by the bifurcation amplitude change in the process of damped or undamped oscillation. The type of the oscillation process depends on the relation between the relaxation factor and the environment resistance factor.
