|Abstrakt EN:||A 50th percentile male model is implemented in Virtual.Lab Motion according to data provided from literature and from parameters obtained by optimization procedures mainly based on virtual tests using a detailed FEM model. The joints, members, skin, contact parameters and sensors are described in the model for handling long time simulation scenarios. For the short time periods, when the MBS model is in contact with some type of obstacle, the critical members of the body are evaluated using the HUMOS2 (FEM) model in RADIOSS in order to assess the injuries. Lately is presented a proposal to increase the accuracy of the injury assessment on the thorax level. For such task, work is in progress based in the image data base from the ?Visible Human Project?. Such new FEM models come from the limitations of the actual FEM models used for car crash scenario. The present work shows a tool that is able to simulate full accident scenarios involving vulnerable road users.|
