{"title":"Crashworthiness Performance of Rear Underrun Protection Device under\u0000 Simulated Car Collision","authors":"Z. F. Albahash, M. Sharba, Bahaa Aldin Abass Hasan","doi":"10.4271/15-16-03-0014","DOIUrl":"https://doi.org/10.4271/15-16-03-0014","url":null,"abstract":"A rear underrun protection device (RUPD) plays a fundamental role in reducing the\u0000 risk of running a small car beneath the rear or the side of a heavy truck\u0000 because of the difference in structure heights in the event of a vehicle\u0000 collision. Even in cars with five-star safety ratings, crashing into a truck\u0000 with poorly designed RUPD results in a passenger compartment intrusion (PCI)\u0000 more than the maximum allowable limit as per the United States (US) American\u0000 National Highway Traffic Safety Administration (NHTSA) standards Federal Motor\u0000 Vehicle Safety Standard (FMVSS). In this article, mild steel was used to\u0000 fabricate the new designs of RUPD. The design was analyzed using finite element\u0000 (FE) analysis LS-DYNA software. Simulations of a Toyota Yaris 2010 and Ford\u0000 Taurus 2001 were performed at a constant speed of 63 km/h at the time of impact.\u0000 The ability to prevent severe injuries in a collision with the rear side of the\u0000 truck was estimated to optimize the underrun design. The new design has achieved\u0000 the goal of decreasing the head acceleration beyond the limit, which is less\u0000 than 60 g. It has achieved a reduction in acceleration by 66.116% and zero PCIs\u0000 even in collisions with different safety ratings cars.","PeriodicalId":29661,"journal":{"name":"SAE International Journal of Passenger Vehicle Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47016254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
