摘要：
Child restraint system (CRS) has great influence in crash-safety of children. Therefore, much further improvement of the safety of CRS is requested. The objectives in this study were clarifying the effect of CRS parameters and exploring the optimums for the crash-safety by using numerical simulation. The numerical simulation was carried out by coupling a crash simulation tool, MADYMO with a multi-objective optimization tool, modeFRONTIER. The neck injury risks in frontal and side crashes were set as the objective functions to minimize. Firstly, significance analysis of the design parameters using dummy models was conducted. From the result, non-effective parameters were removed. Secondly, CRS optimization for the safety in both frontal and side crashes was performed using dummy models. Finally, using CRS with the optimal design, behaviors were compared between dummy models and 3-year-old finite element human model.
