ELEKTRİKLİ ARAÇLARIN GÜVENLİK BARİYERLERİNİN ÇARPIŞMA PERFORMANSINA ETKİSİ

Öz

Elektrikli araçların kullanımı, avantajları nedeniyle tüm dünyada yaygınlaşmaktadır. Büyük bataryalar elektrikli arabaları ağırlaştırmakta ve konumları nedeniyle aracın ağırlık merkezini, geleneksel içten yanmalı motorlu arabalara göre daha alçak hale getirmektedir. Çarpan aracın ağırlığı, güvenlik bariyerlerinin kabul edilebilir performansı için önemli parametrelerden biridir. Elektrikli araçların geleneksel güvenlik tertibatları için başarısızlık riski oluşturabileceği öngörülmektedir. Ancak mevcut tam ölçekli çarpışma testi standartlarında elektrikli araçların kullanımına dair henüz bir güncelleme bulunmamaktadır. Bu çalışmada, elektrikli arabaların H1 performans seviyesi çelik güvenlik bariyerinin çarpışma performansına etkisi bilgisayar simülasyonlarıyla incelenmiştir. Her biri 900 kg ağırlığında olan ve halihazırda TB11 sonlu elemanlar analizlerinde kullanılan üç farklı araç modeli, seçilen referans elektrikli araçların özelliklerine göre modifiye edilmiştir. Bariyerin çarpışma performansı, yolcu güvenliği ve yapısal yeterlilik açısından değerlendirilmiştir. Analiz sonuçları, elektrikli araç testlerinde araç ağırlığının artmasıyla yaralanma şiddet indekslerinin küçüldüğünü, bariyerdeki hasarın ise büyüdüğünü göstermiştir. Mevcut bariyerlerin elektrikli araçlarla çarpışma performansına ilişkin daha fazla araştırma yapılması önerilmektedir.
