Abstract

This study presents a dynamic and statistical analysis of full-overlap low-speed staged rear impacts conducted by the AGU Research Group in Switzerland. A total of 101 staged two-vehicle rear impacts are analysed in which there are override/underride impacts or crashes with full engagement of the bumpers. A work-energy approach is applied to model dynamically two-vehicle full-overlap rear impacts. In the second stage of this study, regression analyses are performed to find correlations between closing speed versus coefficient of restitution, mutual crush, and the ratio of returned and absorbed energies. The presented analysis in this study can be a useful source for accident reconstruction and modelling low-speed rear impacts.
