Mechanism analysis of pedestrian knee-bending angle by sedan-type vehicle using human FE model

摘要

This article describes the reconstructions of pedestrian accidents of several sizes and human genders colliding with sedan-type vehicles. Finite element (FE) human models of American male 50 percentile, American female 5 percentile, and 6-year old child are used to evaluate the lower leg kinematics and injuries to them. FE models of the frontal structures made of urethane blocks that have equivalent stiffness to the frontal structure of the sedan FE model were established to conduct parametric studies of frontal structure stiffness. The parametric studies show optimum stiffness distributions of urethane blocks to help reduce the knee-bending angle and injuries.
