Virtual human body models supplement crash-test dummies
Countless people die every year in road accidents. To improve the safety of vehicle occupants, it has been customary for decades to carry out crash-tests using dummies. These crash-test dummies are increasingly getting virtual support in the form of computer models that simulate the defensive behavior of humans before a collision. Researchers at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI are among those using virtual human-body models in crash simulations, which yield more realistic conclusions about the injury risk. In their calculations, the researchers focus especially on muscle stiffness, which has not been taken into account in previous investigations.
