In this paper, a commercial active hood lift system (AHLS) is optimally designed and evaluated. After introducing the working principle of AHLS operated by a gunpowder actuator, the mathematical model of the AHLS is formulated. The dominant factors that are sensitive to performance index are defined by mathematical equations. Structural constraint conditions of system such as limited space are defined in details. Since the response time system is the most important factor for reducing the damage of the pedestrian, the kinematic structure of AHLS is optimally designed to decrease the response time under the constraint conditions on the basis of trial and error method. In order to evaluate the proposed method, the performances of the optimally designed model including the deformed distance and the response time are compared with the conventional AHLS model.
