3D KAFES ÇATI MODELİNİN SONLU ELEMANLAR YÖNTEMİYLE ANSYS PROGRAMINDA MEKANİK VE ELASTİK GERİLMELERİNİN İNCELENMESİ

Bu çalışmada, kafes çatı modeli Ansys paket programında, sonlu elemanlar yöntemi kullanılarak 3 boyut olarak tasarlandı. Bu yöntem, kompleks mühendislik uygulamalarının anlaşılabilir hale getirilerek, kontrol edilebilir sistemlerle çözümünü sağlayan bir metottur. Modelin element tipi, kafes boru dış çap, et kalınlığı, elastisite modülü ve poisson oranı parametreleri malzeme özelliklerine tanımlanır. Malzeme çelik izotropik bir malzemedir. 3D kafes çatı modeline Fx, Fy, Fz kiriş eksenlerine uygulanan 25000 ve 20000 kN’luk sabit yük ve 2 MPa basınç altında toplam mekanik ve elastik gerilme analizleri yapıldı. Modelin x, y, z eksenlerinde mekanik zorlanmalara karşı gerilme ve elastik stres gerilme analizleri yapılarak yüke karşı göstermiş olduğu deformasyon şekil değişimleri incelendi. Analizler sonucunda, uygulanan yüke karşı oluşan kiriş eksenlerindeki mekanik ve elastik gerilmelerin arttığı görüldü.

INVESTIGATION OF MECHANICAL AND ELASTIC STRESSES IN ANSYS PROGRAM BY FINITE ELEMENTS METHOD OF 3D LATTICE ROOF MODEL

In this study, the lattice roof model was designed in 3 dimensions using the finite element method in the Ansys package program. This method can be understood by making the complex engineering applications is a method to provide the solution can be controlled by the system. The element type of the model, the outside diameter of the truss pipe, the thickness of the meat, the modulus of elasticity and the poisson ratio parameters are defined as material properties. The material is a steel isotropic material. A total of mechanical and elastic stress analyzes were carried out under the constant load of 25000 and 20000 kN applied to Fx, Fy, Fz beam axes and 2 MPa pressure on the 3D lattice roof model. Deformations of the model against the load were investigated by analyzing the stresses against the mechanical forces and the elastic stresses in the x, y, z axes. As a result of the analyses, it was observed that the mechanical and elastic stresses in the beam axes against the applied load increased.
