This paper aims to define a methodology to perform pedestrian accident simulations with multibody techniques using a detailed geometry and stiffness characterization in the impacting vehicles as well as age dependant fracture limits for the MADYMO human pedestrian legs. This methodology is applied to real world pedestrian accidents reconstructed by UPM-INSIA in the frame of the APROSYS project (TIP3-CT-2004-506503) to show its benefits. The proposed methodology is shown to be more accurate than the current multibody simulations but without the model complexity and computational time requirements of the FE models.

For the development of modern automobiles the opponent protection gains within the scope of passive safety an increasing importance. Whereas the developments for occupant protection are in an advanced status, the aspect of pedestrian protection has played an unimportant role for a long period of time. In most cases the customer of a vehicle is the occupant himself and so this interest is clearly dominating.
