|Abstrakt EN:||The powered two-wheeler (PTW) riders are among the group of the vulnerable road users (VRU). That means that they are the most injury risk exposed users in the road transportation. The PTW’s drivers often travel with a speed higher than a bicyclist, but they had only a little better protection against potential injuries. A helmet is the only one required and forced by the law as a personal protective equipment (PPE), which is expected to protect a rider’s body against impact. The PPE market provides a wider spectra of protectors (gloves, garments, boots, joint protectors), but for daily use, none of them are required to be wearied by the rider. Another safety measure in road transportation system is a road barrier, which for the PTW should meet different testing protocol than the car/truck barrier. Due to the complicated kinematics of rider-PTW-opposite vehicle (OV) system in the crash conditions, the current tools for accident simulation and reconstruction, in the PTW crash cases, expose problems of simulation stability and computational cost (finite element method- based tools), or problems of insufficient models’ bio-fidelity and/or over-simplification (multibody system based tools). Authors propose a hybrid approach, which joins the advantages of both methods and it could be used for the PTW passive safety. The manifestation and the center point of this method is a scalable, hybrid human body model (HBM) Virthuman, which could cover wide spectra of the population.|
