In this study, the rigid wall test was simulated in a
virtual environment and the effect of high strength low alloy steel front
collision rail wall thickness on the crash performance of a vehicle was
investigated and the best wall thickness was determined for the front collision
rails. The FEE340 material in the HSLA (High-Strength Low-Alloy) steel group
was used in the front collision rails and the effects of the six different
material wall thicknesses used in the front collision rails were compared with
regard to the crash performance of the vehicle. The crash analyses of the
frontal collision rails with various thicknesses were performed by the Abaqus
finite element software. Total displacement, crush force efficiency (CFE), the
amount of force delivered to the passenger compartment and the amount of energy
damped by each collision member results were acquired from the simulations. For
the vehicle model used in the simulations, when the amounts of force delivered
to the passenger life cage, acceleration and displacement were evaluated, it
was seen that the best wall thickness for the HSLA steel front collision rail
was 2 mm.
Bu çalışmada,
rijit duvar testi sanal ortamda simule edilerek yüksek mukavemetli düşük
alaşımlı çelik ön çarpışma kolu et kalınlığının aracın çarpışma performansına
etkisi incelenmiş ve en uygun et kalınlığı tespit edilmiştir. Ön çarpışma
kollarında HSLA (High-Strength Low-Alloy) çelik grubundaki FEE340 malzemesi
kullanılmış ve altı farklı et kalınlığının aracın çarpışma performansına
etkileri karşılaştırılmıştır. Simülasyonlarda çarpışma kolu, çarpışma kutusu ve
ön tampon (destek) traversinden oluşan yarım araç modeli kullanılmıştır. Farklı
kalınlığa sahip ön çarpışma kollarının çarpışma analizleri Abaqus sonlu
elemanlar yazılımı ile gerçekleştirilmiştir. Simülasyonlardan, toplam
deplasman, çarpışma kuvveti verimliliği (CFE), yolcu kabinine iletilen kuvvet
miktarı ve her bir çarpışma elemanı tarafından sönümlenen enerji miktarı
sonuçları elde edilmiştir. Simülasyonda kullanılan taşıt modeli için, yolcu
kabinine iletilen kuvvet, ivme ve deplasman miktarları değerlendirildiğinde
HSLA çelik ön çarpışma kolu için en uygun et kalınlığının 2 mm olduğu
görülmüştür.
