摘要
Objective: Because of the lack of pediatric biomechanical data, Hybrid-III (HIII) child anthropomorphic test devices (ATDs) are essentially scaled from the mid-size male ATD based on the geometric considerations. These ATDs inherit a rigid thoracic spine from the adult HIII ATDs, which has been criticized as unrealistic. Therefore, the objective of this study was to explore possible design modifications for improving the spine biofidelity of the HIII 6-year-old ATD. Methods: A previously developed and validated HIII 6-year-old MADYMO ATD model was used as the baseline model to investigate the effects of design modifications on the spine biofidelity of the current ATD. Several sets of child volunteer and cadaver test data were considered as the design targets, including child volunteer low-speed crash test data, pediatric cadaver cervical spine tensile test data, and child cadaver crash test data. ATD design modifications include adding an additional joint to the thoracic spine region and changing the join...
