SAFER HBM in 9kph sled simulations - selection of torso skin and flesh material properties
Rapport, 2020

In a comparison of kinematic predictions of the active enhanced SAFER HBM v9 to volunteer kinematics in braking and lane change, it was found that the model gave a stiffer response than the volunteers. To soften the model, the skin material of the torso and buttock, and the solid layer in the torso (flesh), was updated. To evaluate which combination of flesh material and skin material is best suited for low-loading simulations, all possible skin/flesh combinations were simulated and compared to two 9 kph PMHS tests. Simulation results showed that the most suitable combination for low-speed simulations was a flesh model tuned to average adipose tissue stiffness, and an orthotropic skin model using skin tension lines (Langer lines).
