This paper deals with impact vibrations in continuous system excited by periodic force with arbitrary functions. The analytical model is steady impact vibration in a cantilever having an attached mass which collides elastically to clamped spring of symmetrical faces. In order to clarify main resonance of the system subjected to a displacement excitation, the resulting vibrations are analyzed using the Fourier series method and an exact solution is proposed for this system. In addition, the analytical model of the spring-mass system in proportion to beam model is proposed, and the resulting vibration is analyzed using aforementioned method. Following these theoretical analyses, numerical calculation is performed and the resonance curves are generated using the resulting vibrations. The numerical results are shown by the effects of the stiffness of the clamped spring, the ratio of attached mass and the amplitude of excitation on the resonance curves. For verification of the analytical method, experiments are performed. The numerical results are in a fairly good agreement with the experimental ones.
