Research on Evaluation Method of Occupant Neck Injury in Whiplash Test

Abstract:

As road traffic becomes more and more crowed nowadays, rear impact has become one of the most common forms of traffic accident. According to a survey, up to 78.2% of rear impact can cause occupant neck injury. Up to now, E-NCAP, J-NCAP, IIHS and C-NCAP have set whiplash test in officially. But because of the uncertainty of injury mechanism, none of the countries has reached an agreement on the evaluation method of occupant neck injury. Comparison and analysis of whiplash evaluation methods are made, from aspects of collision waveform, speed, evaluation criteria, calculation method, criteria limit, etc. The annual C-NCAP whiplash tests are set as statistical sample and an analysis of the relationship between lost points and influential factors is carried out in order to find the part that needs to be perfected. Finally, effective suggestions are put forward for the improvement of evaluation method of occupant neck injury in whiplash test.
