Abstract
On this study, to develop the impact absorbing system for spreader, we operated the dynamic response for models of three types consisting of spring and oil damper by the finite element analysis. Also, in the three types of impact absorbing system, we set the restricted stroke of piston to the static variables and the optimum design was operated to have the minimum value of the reaction force for the impact. As the result, the direct model of two degree of freedom system has lowest value, the model of one degree of freedom system has higher value than that and the parallel model of two degree of freedom system has the highest value. And we studied the effect that the change of spring constant and damping coefficient affect to the reaction force and as the result of the optimum design, we found that reaction force has the lowest value in the each of models.
