승객 안전도를 고려한 안전띠 일체형 의자의 정. 후면 충돌해석 및 설계

다국어 초록 (Multilingual Abstract)

The performance of a Belt Integrated Seat(BIS) is evaluated using an occupant analysis software. The seat belt is attached to the seat back in the BIS to improve the occupant safety. A simulation model of a BIS is established using SAFE(Safety Analysis For occupant crash Environment). The analysis is carried out for the frontal and rear impact cases. A new seat model is introduced using segments which have mass, moment of inertia and size. The model is constructed based on the structural analysis and the data obtained from a frontal sled test of a BIS. The data from the simulation model is validated for the consistency by comparing them with high-speed photos taken from the sled test. Characteristics of both a conventional seat and a BIS are discussed. It is shown that the occupant safety can be improved considerably with the BIS. A parameter study is conducted for various seat belts and a selection of an appropriate one is recommended. Structural analysis and optimal design of the BIS are performed to obtain the trend of a preliminary design considering the occupant safety. A finite element model of the BIS is established using a structural analysis and optimal design program GENESIS. The seat components are reinforced based on the shape of the conventional BIS. The results are discussed and a trend of the design of a belt integrated seat is proposed through the process of a structural optimization.<br/>
