Numerical analysis of dummy neck for crashworthiness assessment

Abstract

This paper presents an analysis of numerical child dummy neck and neck injury analysis of the numerical child dummy neck. The neck model is developed using flexible component and rigid body. As for the geometries of the child dummy neck, the measurement was taken from Malaysian child and statistical analysis has been performed to obtain the desired measurement. A static load experiment was performed in order to verify the development of numerical child dummy neck after completed the design and meshing. Based on the static load experiment and simulation, the stress and displacement at the neck was calculated to evaluate compression and tension of the child’s neck during crash. This parameter was used for most injuries to the neck, and it is one of the best predictor of neck injury.
