Mathematical Modeling of Crash-Induced Dynamic Loads on Race Car Drivers

A MADYMO model of a racing car and driver was driven by 3-D accelerations recorded in actual crashes. Helmet, belt restraint, and padding characteristics were obtained from dynamics tests. Model results of HIC, head accelerations and neck forces and moments were studied along with driver injuries to provide insight into the efficacy of current injury assessment parameters used with the head and neck of crash test dummies. The results are also used to discuss the kinematics performance of the crash test dummy neck as modeled by the MADYMO version of the Hybrid III midsize male crash test dummy.
