Özet
Bu çalışmada, hafif ve kutulu yükler için paletli depo raf sistemlerinde kullanılan yatay taşıyıcıya oturan tava raf sistemlerinin kapasitelerinin belirlenmesi üzerinde durulmuştur. İstenilen yükleme boyutları altında tava rafların taşıma kapasiteleri hem analitik olarak hem de sonlu elemanlar analizi ile belirlenmiştir. Tava rafın 2a x 2a boyutlu bir bölgesi üzerinde yayılı kuvvetlere maruz kaldığı kabul edilmiştir. Kuvvetler arası mesafenin k olduğu ve 2a uzunluğunda n adet kuvvet bulunduğu kabul edilmiştir. Buradan hareketle her bir tekil kuvvetin şiddeti toplam kuvvet cinsinden bulunmuştur. Daha sonra tava raf kesitini oluşturan her bir parçanın taşımış olduğu momentler bulunarak her bir elemanda oluşan eğilme gerilmeleri hesaplanmıştır. Buradan elde edilen gerilme değerleri emniyetli gerilme değerleriyle kıyaslanarak tava rafın taşıyabileceği maksimum yük tespit edilmiştir. Ayrıca analitik yöntemden elde edilen sonuçlar sonlu elemanlar yöntemiyle kıyaslanmış ve sonuçların birbiri ile uyumlu olduğu görülmüştür.
In this study, determination of capacity for light duty shelf settled on pallet beam are considered. Carrying capacities of light duty shelf under the desired loading diemensions were determined both analytically and finite element analysis. It was assumed that light duty shelf was expose to distrubuted load on 2a x 2a region of shelf. It was assumed that distance between single forces is k and number of single forces was considered n in length of 2a. Afterwards, each value of single forces was found in terms of total force. Bending strength in each members of light duty shelf were calculated by finding moments occured each members. Obtained stress values are compared with safety stress values and maximum load capacity of light duty shelf is determined. Moreover, the results obtained from analytical method are compared with finite element results and the results are found to be compitable with each other.
