This paper deals with impact vibration in a spring-mass system for two-degree-of-freedom excited by periodic force with arbitrary functions. The analytical model is steady impact vibration for two-degree-of-freedom having two masses in which subjected to an exciting vibration. Then the repulsion force, which has characteristics of an unsymmetric piecewise-linear system with hysteresis loop, collides elastically to anather mass when amplitude of the mass increases farther than clearance. In order to analyze the resulting vibration for the main resonance, the Fourier series method is applied for this system. Next, following the theoretical analysis, numerical calculations are performed, and the resonance curves are made by the resulting vibration. Effects of amplitude ratio of excitation, stiffness of clamped spring and mass ratio on the resonance curves are shown by numerical results. In the present diagram of the resonance curve, discussion is made on the characteristics of resonance phenomena.
