The post examination of motorised two wheelers following a frontal impact have changed due to recent design evolutions. Fork or front frame damage have been drastically reduced while the front wheel rim, upper T or steering column ruptures are soaring. The main reasons for this evolution are due to the wide use of alumium alloys for frames associated with inversed forks. In order to better evaluate the rupture energy thresholds used in accident reconstruction, destructive tests (hereby brash tests) have been conducted.
This project was handled through a partnership from the accidentology group of the ANEA (Alliance Nationale des Experts en Automobile – French National Alliance of Automotive Assessors) and the Marseille site of the INRETS (Institut National de Recherche sur les Transports et leur Sécurité – National Institute for Transport Research and their Safety) As a matter of fact, this site is equipped with a sled including up to date data acquisition material.
Thanks to the collaboration with the LBA (Laboratoire de Biomécanique Appliquée - Applied Biomecanics Laboratory) and the UM (Université de la Méditerranée- Mediteranean University), all crash tests have been conducted with PMHS equipped with deceleration sensors on potential injured zones. This project studied the occupant injury mecanisms and his trajectory as well. The project goal is to be able to better reconstruct two wheelers accidents and to use the injury reports as a tool to confirm impact velocities, damage and impact angles.
