Abstract
A simple dynamic human model in side impact crash is introduced based on finite element (FE) model. The simple dynamic model consists of three masses corresponding to the thorax, the upper body and the lower body. The thorax mass was introduced in order to consider the thoracic deflection. The thorax and the upper body were connected by a linear spring and a linear damper in parallel. Numerical simulations show that the simple dynamic model can approximate the thoracic deflection, the upper body displacement, and the lower body displacement of the human FE model in side impact crash.
