Numerical Simulation of Human Kinematics and Injuries in Side Crash Scenarios 2004-01-2161

Optimizing protection for side impact in vehicle design requires valid information about occupant behavior under lateral loading. For this reason a comparison of numerical models of dummies and human body in side impact scenarios is shown to estimate the benefits of using numerical human models in future safety design.

First a well-known sled test set up was simulated to compare the two devices in a defined surrounding. After looking at the kinematics, the loads, accelerations and injury values of the occupants were derived and compared to each other. Second the occupant models were positioned in a vehicle model to compare their behavior in a more complex loading case, such as an EuroNCAP Barrier Test. Focus of this investigation was the injury mechanism occurring in the human model.

The Behavior of the Dummy and H-Model is comparable and shows similar responses in a global view. However, the H-Model gives more Information about the mechanism of possible injuries and there are some load differences which can be established by the different construction of Dummy and Human Model.
