Statik ve Dinamik Yük Altındaki Çekme Alüminyum Profillerde Kesit Alan Tasarımının Mekanik Davranışa Etkisi
Abstract
Bu çalışmada aynı kesit alana ve dış ölçülere sahip farklı kesit geometrilerinde tasarlanmış alüminyum
profil yapıların eğilme, burulma ve çarpışma enerjisi sönümleme kabiliyetlerinin kıyaslanması ve
performans değerlendirmeleri yapılmıştır. Bu amaçla oluşturulan geometriler beş adet silindirik ve dört
adet kare kesitli olarak iki gruba ayrılmıştır. Dış hat ölçüleri aynı olan geometriler, kesit alan miktarları
aynı olacak şekilde değişken iç kesit tasarımlarına sahiptir. Sonlu elemanlar metodu kullanılarak profil
yapıların farklı tip yük altındaki mekanik davranışları incelenmiştir. Analiz sonuçları, Eğilme ve döndürme
yükleri altındaki Maksimum von-misses gerilmeleri, rijitlik değerlerinin kıyaslanması, çarpışma
testlerinde ise Maksimum ve ortalama çarpışma kuvvetleri, Sönümlenen enerji ve Spesifik enerji
sönümleme oranlarının kıyaslanması olarak değerlendirilmiştir. Çalışmada eğilme ve burulma yüklerinde
yüksek performans gösteren profil yapıların eksenel çarpışma yüklerinde daha düşük performans
gösterebildiği görülmüştür.
