DEVELOPMENT OF A FINITE ELEMENT MODEL OF THE TOTAL HUMAN MODEL FOR SAFETY (THUMS) AND APPLICATION TO CAR-PEDESTRIAN IMPACTS

“THUMS (Total Human Model for Safety)”, as shown in Figure 1, is a finite element model of a human body developed to study various injury mechanisms, and is used as a substitute for the crash test dummies used for car occupants and pedestrians. “THUMS” is designed so that the whole body can be deformed and modeled in detail up to an AM50%ile size.

In this paper, “THUMS” is used as a pedestrian model and it is validated through the verification of pedestrian’s whole body kinematics and lower extremity injuries. The simulation results are in good agreement with car-pedestrian impact test results using cadavers.
