Abstract
Kemalangan jalan raya adalah salah satu fenomena masalah yang terbesar di dunia dan masalah bagi mencegah sesuatu kemalangan. Rel Adang seperti W-beam Guardrail adalah penghadang jalan yang direka untuk mencegah kenderaan dari meninggalkan jalan tersebut untuk meningkatkan keselamatan jalan raya. Kesan ujian skala penuh telah dan akan terus menjadi kaedah yang paling biasa menilai prestasi keselamatan rel adang, halangan lain dan bahagian tengah jalan raya. Tujuan kajian ini adalah untuk membangunkan dan menilai model skala penuh pengiraan halangan keselamatan jalan raya untuk digunakan dalam simulasi kemalangan dengan Perisian ABAQUS / EXPLICIT dan terus membandingkan keputusan pengiraan dengan data ujian. Di dalam kajian ini perubahan sifat atau karektor rel adang diperiksa menggunakan ujian spesimen makmal kedua-dua statik dan dinamik. Kemudian simulasi digunakan bagi menganalisa elemen rel adang secara analisa perlanggaran yang sebenar merujuk kepada laporan NHRCP 350. Ini adalah untuk mengenalpasti kesan ke atas sifat-sifat mekanikal Rel adang dan untuk menilai keupayaan tenaga penyerapan rel adang akibat impak perlanggaran. ________________________________________________________________________________________________________________________ Road-traffic crashes are one of the world’s largest public health and injury prevention problems. Median Barrier such as W-beam Corrugated Guardrail is a barrier on a road designed to prevent vehicles from leaving the roadway to improve road safety. Full-scale impact testing has been and will continue to be the most common method of evaluating the safety performance of guardrails, median barriers and others. The purpose of this research was to develop and evaluate a full-scale computational model of the road safety barrier for use in crash simulations with ABAQUS/ EXPLICIT Software and further compare the computational results with test data. In this present study the behavior of W-beam guardrail is examined using laboratory specimen tests both statically and dynamically simulated using finite element analysis by analyzing the W-beam Corrugated Guardrail and Solid Car Bumper under crash condition based on NHRCP 350 reports. This is to identify the effects on mechanical properties of W-Beam Corrugated Guardrail and to describe the energy absorbing capability of W-Beam Corrugated Guardrail as well would produce after the crash impact occur.
