Crash analysis using computer simulation is the significantly economic method to save time and money as compared with sled test. But this analysis is able to make an interpretative problem different from reality by a few of unconsidered factors. So this study is to be able to analyze a more accurate car crash applying to air flow movement that had not been considered before. It is assumed that is different characteristics on condition and It is designed a system of impact experiment of car seat foam considering air flow movement within the foam and pre-strain. This system enables control of pre-strain using electro-magnetic impactor, determination of air flow movement within the foam using punching plate and flow control sensor. It is differ on condition of maximum impact load on the foam, a kind of cover of foam, quantity of pre-strain so as to figure out air flow movement by seat foam used back and cushion by vehicle type. As result, it is observed that maximum load by voltage of electro-magnetic impactor seems repetitiveness of replays on the experiment and that air flow movement from seat foam is belched symmetrically by holes’ position of punching plate. If it is verified additional study on characteristics of seat foam varied by different air flow movement from seat foam, it is able to analyze of car crash using computer simulation more like a reality.
