YÜKSEK PERFORMANSLI ENERJİ YUTUCULAR İLE TAŞIT ÇARPIŞMA GÜVENLİĞİNİN GELİŞTİRİLMESİ
Trafikteki taşıt sayısının son yıllarda artması ile birlikte, trafik kazaları da önemli ölçüde artmıştır. Bu kazaların en yaygın türü de önden çarpışmadır. Bu çalışmada, enerji yutucuların çarpışma performansı sonlu elemanlar yöntemiyle ve deneysel olarak incelenmiştir. Farklı geometrilerdeki enerji yutucular tasarlanmış ve başlangıç modeli olarak ele alınan enerji yutucuya göre daha fazla enerji emebilen, reaksiyon kuvvetleri ve maliyetlerinin azaltıldığı yeni bir enerji yutucu modeli geliştirilmiştir. Çarpışma analizleri sonucunda, geliştirilen enerji yutucunun kütlesi 0,02 kg azaltılmış, özgül enerji emilimi ise 170 J/kg arttırılmıştır.

IMPROVING THE VEHICLE CRASH SAFETY WITH HIGH PERFORMANCE ENERGY ABSORBERS
Depending on the increasing number of vehicles in recent years, traffic accidents have been increasing significantly. Frontal crash is the most common types of vehicle accidents. In this study, crash performances of the energy absorbers were investigated using finite element method and experimentally. Energy absorbers with different geometry are designed and a new energy absorber which has better crash performance, peak force and cost than initial design is developed. The numerical crash analysis results show that the weight reduction is 0,02 kg and increasing the amount of the specific energy absorption is 170 J/kg for the best design.
