TitleA Model for Determining Injury Risk on the Basis of Impact Speed, Using Vehicle Data from Variable-Speed Impact Tests
AuthorsGockowiak KLK, Anderson RWG, Searson DJ

TypeConference Paper
AbstractThis paper discusses a model that estimates the effect of a change in impact velocity on vehicle impact response. The motivation of the study is to develop a model that will be able to predict occupant injury risk over a range of speeds based on performance in standard crash tests. The model comprises a tipped equivalent square wave (TESW) acceleration pulse to model the vehicle acceleration that is dependent on impact speed. The model was used to analyse data from five full-width rigid-barrier impact testing carried out at five speeds. Analyses were selected to investigate the relationship between impact speed, vehicle dynamic crush and mean impact acceleration. The results suggest that it is possible to model vehicle impact response (specifically the magnitude of dynamic crush and mean vehicle impact acceleration) using a bi-linear, impact-velocity-dependent relationship, based on a limited number of crash tests. Models such as these may provide a means of integrating assessment of vehicle crashworthiness with the assessment of primary safety technologies designed to reduce the speed of crashes.
