Front underride protection devices: methods for design and testing

Abstract

Improvements to highway safety are in continual demand. One of the most severe instances of vehicle collision occurs as a result of vehicle weight and sizing mismatch. The fitment of Front Underride Protection Devices (FUPDs) upon tractor-trailers is studied as a method to improve crash compatibility between passenger vehicles and tractor-trailers involved in head-on highway crashes. While some countries require the use of FUPDs, no such regulation exists in North America. North America‟s use of Conventional Tractors also presents a variation to Cab-over Engine Tractors popular in Europe. The distinction presents variations to FUPD design boundary conditions. A three tier design strategy is proposed and implemented in an effort to guide development of FUPDs for improved performance and robustness. Extensive testing is undertaken in establishing guidelines for further development and testing of Front Underride Protection Devices.
