Enhancement on the RUPD system of heavy vehicle by Evaluation of a Head Injury Criteria

Abstract

Crashworthiness improvement of under-ride guard system of heavy vehicle design is a highly challenge duty to save passengers life and prevent sever injures of small car in collisions. As a consequence of absence or lack of the powerful under-run guard connected to the rear, side of trucks, trailers and semi-trailers, back under-ride accidents are in charge of a huge death numbers in all the world. This study concentrates on improving Rear Underrun Protection Device (RUPD) structure utilizing Finite Element Analysis apparatus like LS-DYNA. Two designs of under-ride guard devise crushed using Toyota Yaris (2010) with different impact speeds 45km/h and 63km/h. A zero passenger compartment intrusion (PCI) is accomplished with the investment of the recently outlined under-ride guard for rear of trucks. The new under-ride guard model is validated utilizing FMVSS 223/224 regulations. The new design achieved the goal of decreasing the acceleration beyond the limits, which leads to decrease the head injury criteria (HIC) to (373.250).
