DEVELOPMENT OF COMPLIANCE TEST FOR TRUCK REAR UNDERRIDE PROTECTION. VOLUME II - TECHNICAL REPORT

The objective of this program was to develop static and dynamic compliance test procedures for truck/trailer rear underride protection. A static test facility and dynamic test device along with appropriate compliance test procedures were developed to test and evaluate rigid and energy-absorbing velocity-sensitive underride guards. A truck body simulator was also developed to effectively model the rear of truck/trailer bodies for mounting of selected guards during testing. The dynamic test device is an energy-absorbing honeycomb-faced bogey vehicle which simulates the front load/deflection characteristics of a typical current large car. The report summarizes the highlights of the tests of current small and large car-to-current production guards, ten car-to-rigid guard tests to determine the effects of speed, guard height, car size, and impact mode on underride and occupant response, and two tests of a production energy-absorbing guard. Based on the results of the crash tests and engineering analyses, recommendations are presented for underride guard requirements and compliance test procedures.
