Development of Numerical Child Dummy model and the analysis of head impact criterion

Abstract

This paper presents a development of numerical child dummy model and head impact criterion analysis of the numerical child dummy model. The model was developed using flexible component for crucial parts such as neck and thorax and less important parts was modeled using rigid body. As for the geometries of the child dummy, the measurement has been taken from Malaysian child and statistical analysis has been done to obtain the desired measurement. A simplified crash was performed in order to verify the development of numerical child dummy model after completed the design and meshing. Based on the simplified crash simulation, the head impact criterion (HIC) was calculated to evaluate head injuries of the baby during crash. Head Impact Criterion was used for all impacts to the head and it is the best predictor of brain concussion. From the simplified crash, it is found that the higher the velocities, the HIC readings also increase which indicate more severe head injuries.
