ISIGHT와 MADYMO를 연계한 CAE 시뮬레이션 자동화 및 최적화에 관한 연구

This study introduces a computer-aided simulation automation and optimization approach using ISIGHT and MADYMO simultaneously. A MADYMO model that reconstructed a specific car-to- pedestrian accident case was chosen. At first, the impact velocity of car was calculated from the principle of the conservation of energy. MADYMO simulation was also performed to verify the final position of the pedestrian. Simulation automation process was constructed using ISIGHT and 6-input variables and 2 -output variables(objectives) were also parsed. Car impact velocity was found as the most effective factor from DOE(Design of Experiment). Finally the optimal position of the pedestrian could be achieved from optimization. ISIGHT is expected as a useful solution to save much time and to obtain more compatible outputs in the forensic engineering field.
