  • Data analysis and modelling
  • 2008
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This deliverable on data analysis provides guidance and general principles for: - pre-testing to check the usability of the system and the feasibility of the evaluation process, - controlling the consistency of the chain and the precision with different sampling schemes, - modelling the impact for each indicators and for an integrated evaluation including a systemic and multidisciplinary interpretation of the effects, - integrating and controlling the quality of space-time data from various sources (numerical, video, questionnaires), - selecting the appropriate statistical techniques for data processing, PI estimation and hypothesis testing in accordance to the list of indicators and experimental design, - scaling up from experimental data and identified models to population and network level. Experimentalists stress the role and importance of a preliminary field test in FOT. Three main objectives have been defined to make a preliminary diagnosis of usability of the systems and to check the relevance and feasibility of the evaluation process. These preliminary tests are very important for the practical deployment of the FOT as well as for the overall scientific evaluation process.

  • Dynamic performances of different seat designs for low to medium velocity rear impact.
  • 2001
  • Ingår i: 45th Annual Proceedings. - : Association for the Advancement of Automotive Medicine. ; , s. 187-201
  • Konferensbidrag (refereegranskat)abstract
    • There is good evidence that seat design and impact severities in terms of delta-V and acceleration plays a role in AIS 1 neck injury outcomes in the event of a rear impact. This study evaluates a number of current production seats to assess the AIS 1 neck injury protection potential at different impact severities. Five different seat designs were exposed to four different impact severities in a sled simulating a rear impact. The same delta-V produced with different peak accelerations generated very different dummy responses. Head restraint position influenced the angular and horizontal displacement of the head relative to torso and the time of head to head restraint contact. The lowest motion of the head relative to the torso was found in the two anti-whiplash seats tested. The results of the study can be used for the design of future vehicle seats and anti-whiplash systems.
