This paper deals with the analysis of collision vibration in continuous system excited by periodic force with arbitrary function. The analytical model is steady collision vibration of cantilever which collides at arbitrary position from fixed end to free end in cantilever. Then, the cantilever excited by forced displacement vibration collides elastically to symmetrical face. In order to analyze the response of main resonance, the Fourier series method is applied to the system, and an exact solution is proposed. Following these theoretical analyses, the numerical calculation is performed and the resonance curves are made from resulting vibration. Effects of stiffness of clamped spring and amplitude of excitation on resonance curve are shown by numerical results. For verification of the analytical method, experiments are performed. Analytical results are in a fairly good agreement with experimental ones.
