Underride/Override of Automobile Front Structures in Intervehicular Collisions. Volume 2. Car-to-Car Head-on Impacts.

摘要

Findings from studies aimed at reducing the damaging consequences of headon collisions between automobiles that result from incompatibility of their forward energy absorbing structures are presented in this report. Vehicle and occupant dynamic responses obtained in tests of automobiles impacting at closing speeds in excess of 85 MPH are presented and analyzed. The series of four tests included collisions between standard full size cars and between full size and compact cars,including one small car incorporating a modified bumper system to increase the energy dissipation capacity of the front structure and thereby reduce passenger compartment intrusion.
