This paper deals with the analysis of collision vibration in continuous system excited by periodic displacement with arbitrary function. The analytical model is steady collision vibration of cantilever which collides with arbitrary location between fixed and free ends. Then, the cantilever collides elastically with the coil springs clamped on symmetrical faces when the amplitude of cantilever vibration exceeds the clearance at the springs location. In order to clarify the main resonance of the system, the resulting vibration is analyzed applying the Fourier series method for this system and an exact solution is proposed. Following the theoretical analysis, numerical calculation is performed and the resonance curves are constructed from resulting vibration. The numerical results show effects on the amplitude of forced vibration, the collision position and the stiffness of clamped springs for resonance curves. Experiments are also carried out to verify the theoretical results.
