This paper deals with transient vibration approximated by periodic vibration due to repeated impulse. The analytical model is transient vibration in spring-mass system with damping, hi order to clarify the resulting vibration subjected to repeated impulse exciting force, the transient vibration is analyzed using the Fourier series method to the system t which is proposed by the authors. Following the theoretical analyses, numerical calculation are performed, and the waveforms of transient vibration are made using numerical results of the insoculating and the Fourier series method. Effects of the viscous damping ratio, the natural circular frequency and the aspect ratio of impulse on the waveform of transient vibration are shown by numerical results and experimental ones. The numerical results are in a fairly good agreement with the experimental ones.
