Validation of Kinematics and Lower Extremity Injuries Estimated by Total Human Model for Safety in SUV to Pedestrian Impact Test

Abstract

In recent years, the distributions of vehicle types include a substantial number of Sport Utility Vehicles (SUVs). Pedestrian injury distribution of SUVs is different from that of passenger cars and head, torso, and lower extremities are most frequently injured body regions of pedestrian impacted with SUV. Therefore, kinematics of pedestrian and mechanism of injuries of pedestrian, who is impacted by SUV, are emerging research area. In this paper, the kinematics and lower extremity injuries of pedestrian were simulated by using a human FE model “Total Human Model for Safety” (THUMS) and SUV FE model. The result by the simulation was validated with test result and showed generally good correlations. Kinematics of whole pedestrian and mechanism of injuries of lower extremities of pedestrians impacted by SUV were discussed.
