A Study on Saemaeul-ho Seat's Simulation Model for Train Occupant Injury Evaluation

열차 승객상해평가를 위한 새마을호 의자의 해석모델링 방법에 대한 연구

The purpose of this study is to develop a simulation model which substitutes a sled test of train seat. The occupants behaviors of Saemaeul-ho two passenger seats were simulated using MAYDMO(MAthematical DYnamical MOdel) and these results compared with those of sled test. To improve the simulation model which used in previous study, the plastic behaviors of the pedestal were considered and the rear seats are represented as ellipsoid multi-body model instead of finite element model. Using the improved model, we could reduce the computer run time and get more accurate results.
