Design Methodology of Heavy Truck Front Underride ProtectionDevices (FUPD)

摘要

The Objective of this study is to explain a new methodology in the design of heavy vehicle front underride protection devices (FUPD). This methodology is targeted generating optimal solutions in a cost-effective manner. In this research project non-linear finite element models were created using LS DYNA FEA package to perform crash simulations between a small car and the front of the truck at various levels, starting from component model level and ending with full tractor-semitrailer model level. Comparison between the crash simulation results with and without FUPD cases was performed to assess the adequacy of the design at every level of the study. Based on the results obtained an efficient and confident methodology for the evaluation of heavy truck FUPD designs is proposed. Furthermore, the proposed evaluation criteria are recommended to be the pioneering standard for FUPD performance evaluation.rnKeywords: design methodology, front-end impacts, front underride protection device (FUPD.
