A Study on Behavior of Flexible Legform Impactor(Second Report)

-Comparative Study with Leg Behavior of Human FE Model-

Abstract

The study examined the test condition for the pedestrian lower leg protection using a Flex impactor FE model. The effects of the impactor height and an additional mass were discussed comparing the kinematics and responses to those of a human FE model. The results showed that the impactor at a height of 75 mm from the ground generates closer moment and bending responses to that of the human model. The study also found that a mass of 6 kg attached to the impactor top could improve the femur kinematics when impacted to SUVs.
