Nowadays it is required for a car bumper system to meet the various impact safety regulations. Until now, bumper system is designed for satisfying each impact condition independently. So it is very difficult to design a bumper system tosatisfy all requirements simultaneously, and it has been done by trial and error until now. To overcome these problems, many studies on the optimization of bumper system are being performed. In this study, the bumper optimum design program is developed to optimize the bumper system satisfying the bumper barrier impact, pedestrian protection bumper impact and new IIHS(Insurance Institute for Highway Safety) bumper impact conditions. For this bumper optimum design program, equivalent beam analysis model is developed for each bumper loading condition.
