The goal of this study was to simulate and calculate the deflection of an undamped as well as a damped system with 2DOF caused by elastic collision and by general collision. The response of the system according to two different collision positions was calculated.<br />In the second part of this thesis, a general procedure was developed to analyze the response of the 2DOF system to two types of excitation, rectangular and half cycle sine pulse force. Additionally the time variation of the response to half cycle sine pulse force is studied, and graphically shows that the maximum response is as a function of t_d/T_n, the ratio of pulse duration to natural vibration period. In the last part is the effect of damping on the response to a single pulse excitation demonstrated.
