[구조강도부문] 알루미늄 범퍼시스템 개발

The function of a bumper system is to minimize a damage of vehicle in collision at low speed by absorbing the kinetic energy. By using aluminum as lightweight material, the weight reduction as well as the requirements of regulations defining the performance level can be achieved. First of all, we considered what kind of bumper section is the most effective. And then, we applied the result in design step. And finally, we verified that the aluminum bumper system decided by the previous procedure met the target of this project. In conclusion, we could achieve the weight reduction of about 30 percent.
