측면 충돌 시 MADYMO Scaling 방법을 이용한 탑승객 상해 Correlation

CAE analysis for the safety performance of a vehicle has two parts. One part will be conducted by FE analysis such as a LSDYNA software, to develop the ability of a vehicle structure and another part will be pursued by occupant behavior analysis such as a MADYMO software which supports robust airbag models and dummy models to develop the performance to protect its occupants. Due to this separated procedures for the vehicle crash simulation, each procedure makes the most of its merit. In the case of the structural crash simulation, it will focus on the total deformation of vehicle structures and the deformation mode. However, occupant behavior analysis needs the more precise deforming velocity of vehicle structures to conduct its analysis successfully. In this case, to have a more correlated MADYMO model, PSM (Prescribed Structural Motion) data which has the position of all nodes at every time step should be pertinently adjusted. This method will help to have a better correlated MADYMO CAE model in improving the safety performance to protect occupants.
