The study for traffic safety improvement is so necessary to minimize the wound of pedestrian at car impact as to prevent pedestrian from this accident. This study aims at analyzing the behavior affected by impact on which car body hits pedestrian. Load and damage of pedestrian are also investigated. This model is the small car body as frame structure. The pedestrian is modeled with dummy by CATIA as Korean standard body style. The car impacts the side of pedestrian with the speed from 30 to 90㎞/h. Behavior and damage of pedestrian at impact are analyzed by ANSYS. In case of 30㎞/h, The maximum pressure of dummy becomes the maximum value of 100㎫ after the elapsed time of 0.1second and then seems to remain at 105㎫ constantly. In case of 60㎞/h, its pressure becomes the maximum value of 110㎫ at the elapsed time of 0.05second and decreases at 90㎫ until the elapsed time of 0.1second. This value fluctuates after the elapsed time of 0.1second. In case of 90㎞/h, its maximum pressure becomes the maximum value of 155㎫ at the elapsed time of 0.07second and fluctuates after the elapsed time of 0.07second until 0.3second. This value seems to remain at 100㎫ constantly after 0.3second until 0.5second. But this pressure increases suddenly just after 0.5second. Maximum deformations of dummy increase linearly according to elapsed time at hitting velocities of 30, 60 and 90㎞/h.
