Development of a Finite Element Model for the Pedestrian Lower Limb – Model validation for car-pedestrian impact –

Article of Honda R&D Technical Review Vol.13 No.2

Summary

A finite element model for a human lower limb in a standing position has been validated against published experiments simulating impact between a pedestrian lower limb and a car front. The results showed that the model can reproduce the peak linear acceleration during the impact at both the impact level and the knee joint. The comparison of injuries to leg bones and knee ligaments between the experiment and the computer simulation showed that the model can predict different injury patterns observed under different impact conditions. Further, in addition to reproducing the response of the lower limb, the upper half of the human body was modeled with rigid segments connected by joint elements in order to simulate the kinematics of the upper body. The neck model has been validated against published experiments that used human volunteers. While validating the full body model against published full-scale car-pedestrian impact tests, it was found that the full body model can simulate both injuries to the lower limbs and the kinematics of the human body.
