This study deals with the area of nonlinear and random mechanical vibration. It was supposed a simple classical vibratory system with translational motion, simulated as a single degree of freedom system. It was additionally considered that the main parameters characterizing inertia, dissipation and rigidity were affected by some uncertainties during the system evolution under the external
dynamic load. The paper presents a method and a computational tool being able to provide useful information regarding the possible response of this system subjected by external harmonic loads. The results were comparatively analyzed with those obtained by the method of extremes identification of variation interval.
