Abstract:

The influence of the deference of the 3-year old finite element (FE) model on the evaluating performance of the Child Restraint System (CRS) was analyzed. Q3 dummy FE model and THUMS 3YO Human FE model were used to develop front sled test FE simulations with different types of CRS based on ECE R129 regulation. The kinematic behaviors of the FE models were compared, as well as the injury parameters of neck bend angle, chest deflection and chest resultant acceleration. The results show that in front-impact- shield CRS, Q3 were flipped upward, while THUMS 3YO with a motion of declination. The injury parameters of neck bendingangle, chest deflection and resultant acceleration of the THUMS 3YO were larger than Q3. The study shows that the neck and chest of THUMS 3YO FE model are more flexible and less stiffness than Q3 dummy FE model.This conclusion can be as reference for the future application and development of child dummies.
