충돌시 운전자 안전 시트 연구

초록

In order to protect passengers in the vehicle collision, several applications are installed in vehicle for safety. Airbag is one of the applications installed in vehicles and its performance is evaluated by the distance between passengers and airbag itself. In this study, the distance between passengers and airbag is controlled by moving passenger seats with BLDC(Brushless DC) motor. The experimental result shows that the velocity of the seat meets the minimum requirement for this case. To validate its feasibility, the simulation of intergrated system of airbag and controlled passenger seat is conducted through LS-Dyna. In the simulation result, the impact on the passenger's head is decreased. The actual dummy test will be conducted to validate this system.
