Experimental testing of selected energy absorbers in the context of their use in rear underrun protective devices

Abstract

The energy-absorbing structures have been being developed for many years by various research centres all over the world. The article presents experimental test results obtained for selected structures designed for the absorbing of kinetic energy in order to reduce the loads on occupants of a motorcar when hitting the rear of a motor truck. The differences between selected energy-absorbing structures have been analysed, based on impact resistance indicators having been determined. The main objective of this research work was to verify the applicability of selected energy absorbers to the rear underrun protective devices as the truck parts accountable for vehicles’ passive safety.
