Abstract |
Child Restraint System (CRS) can effectively protect child occupants from severe injury in vehicle collision; thus, the Q-series anthropomorphic test devices (ATD or dummy) are necessary for testing the performance of CRSs. In this study, complementary approaches (sled testing with a Q1.5 dummy, computer simulation with a Q1.5 dummy model and 1.5 YO human model) are developed to study the difference of the Q-series child dummy and human model while restrained in shield CRS. The results suggest that in frontal sled impact, the differences in the dynamic response of the Q-series dummy and human model are mainly due to the stiffer thoracic spine and lumbar spine. The implications of these differences for the evaluation and design of Q-series child ATD will be discussed. Also, some suggestions about the improvement of the Q-series child ATD are provided.
