Lifting
hook is one of the important components used in materials handling systems for
safely transporting and lifting the loads. In this study, 3D modelling of a
lifting hook that has 40 kN lifting capacity specified in DIN 15400 and DIN
15401 standards and stress analyses of lifting hook model by using boundary
conditions have been performed. Critical points have been determined based on
stress analysis results. After critical points are determined curved beam
theory is used to calculate stresses on critical points of lifting hook. An
illustrative example has been given to compare the stress results obtained by
curved beam theory and finite element simulations.

Yük kancaları, yüklerin
taşınması ve güvenli bir yük transportu için taşıma sistemlerinde kullanılan
önemli parçalardan biridir. Bu çalışmada, DIN 15400 ve DIN 15401
standartlarında tanımlanan, 40 kN kapasiteli bir yük kancasının üç boyutlu
modellenmesi ve sınır koşulları uygulanarak yük kancasının gerilme analizi
yapılmıştır. Gerilme analizi sonuçlarına dayanarak kritik noktalar
belirlendikten sonra yük kancası üzerindeki kritik noktalardaki gerilmeler eğri
eksenli çubuk teorisi kullanılarak hesaplanmıştır. Sonlu elemanlar simulasyonu
ve eğri eksenli çubuk teorisi kullanılarak elde edilen gerilmelerin
karşılaştırılabilmesi için açıklayıcı bir örnek sunulmuştur.
