This paper deals with impact vibration in continuous system excited by periodic force with arbitrary function. The analytical model to be discussed is steady impact vibration in cantilever which collides elastically into unsymmetric bodies with top of the lever. In order to analyze the main resonance subjected to excitation by displacement, the Fourier series method is applied to this system. Following these theoretical analysis, numerical calculations are performed and the resonance curves are made form resulting vibrations. Effects of the stiffness of clamped parts, gap and amplitude of excitation on the resonance curve are shown by numerical results. For verification of the numerical method, the experiments are carried out according to the analytical model. The analytical results are in a fairly good agreement with the experimental ones.
