50%tile 충돌 더미를 이용한 Knee impact 성능에 관한 연구

Lately, Car makers have to assure of the safety performance at more severe condition than before with the effectuation of the NEW FMVSS208 regulation Knee Impact performance is one of the important safety regulations that have to be developed in the early design stage. In this study, we tried to search optimum design guide by using simulation in the early stage as same condition of sled test. We also want to set up new CAE analysis process for kneebolster and apply to continuously another car in the future.
