Özet:

 In this study, the performance of the front collision zone of the vehicle, reinforced with an S-shaped front collision rail, was compared to that of the classic straight front collision rail. In order to create a safe living cage in automobiles, half vehicle model was used and the collision performances of two different front collision zone models were compared. Torsion, bending and frontal impact scenarios were created with Hyperworks-Optistruct software to obtain versatile and continuous load paths in the vehicle. Vehicle front collision zone elements were designed with Siemens NX software based on the resulting load paths. Altair Hypermesh software was used to create the material properties, connectioncontact zones and element mesh structures of the front collision zone components, and thus the preprocessing step was completed. Two different collision zone models were used to compare the collision zone with the classic arm and the one reinforced with the S shaped collision arm. The amount of energy absorbed by the collision zone components, the total displacement in the collision zone, the loads transmitted to the passenger cabin and the efficiency of the collision force CFE were obtained from each simulation.

 Bu çalışmada, S şeklinde bir çarpışma kolu ile güçlendirilmiş, aracın ön çarpışma bölgesinin performansı, klasik düz çarpışma kolununki ile karşılaştırılmıştır. Taşıtlarda çok yöne ve sürekliliğe sahip yük yollarını çıkarmak amacıyla ön taraftan çarpma senaryosu Hyperworks  Optistruct yazılımı ile modeli oluşturulmuş ve aracın topoloji optimizasyonu yapılmıştır. Çıkarılan yük yolları kullanılarak aracın ön çarpışma bölgesinde yer alan komponentler tasarlanmıştır. Ön çarpışma bölgesi komponentlerinin malzeme özellikleri, bağlantıtemas bölgeleri ve eleman ağ yapılarının oluşturulmasnda Altair Hypermesh yazılımı kullanılmış ve böylece ön işlem adımı tamamlanmıştır. Klasik düz çarpışma koluna sahip ön çarpışma bölgesi ile S şeklindeki çarpışma koluyla güçlenedirilmiş ön çarpışma bölgesini karşılaştırmak amacıyla iki farklı çarpışma bölgesi modeli kullanılmış ve analizlerin çözümü için Abaqus çözücüsü kullanılmıştır. Her bir simülasyondan çarpışma bölgesi komponentleri tarafından sönümlenen enerji miktarı, çarpışma bölgesinde meydana gelen toplam deplasman, çarpışma sonucu yolcu kabinine iletilen yükler ve çarpışma kuvvetinin verimliliği CFE sonuç olarak elde edilmiştir.
