Human Body Model with Active Muscles and Detailed Brain for Pedestrian Protection Research

Pedestrian accidents comprise a significant part of the fatalities found in traffic accidents, making it a prioritized research field both in Sweden and internationally. The head is one of the most vulnerable body parts in the body why this project focus on improving the predictability of head and brain injury in a state-of-the-art human body FE model. One emphasis in this project is on pre-crash activated neck muscles and its effect on head-to-vehicle interaction. The model is also used in accident reconstructions by correlating injuries and damages from real life accidents in order to gain better understanding of injury mechanisms. The aim is that the gained knowledge will help in understanding how injuries can be reduced and provide the vehicle industry with better tools in their work in improving pedestrian protective systems.
