Bugünlerde özellikle otomobil teknolojisinde çok hızlı gelişmeler olmaktadır. Hem otomobil hem de ağır vasıta araçları olan otobüs ve kamyonlarda disk fren sistemi aracın tekerleğin dönüşünü yavaşlatan ve durduran sistemlerdir. Araçları durdurmak için frenleme yapıldığında bir ısı meydana gelmekte ve sistem atmosfere açık olması sebebiyle kolayca dağılabilmektedir. Üreticiler bu durumu kısa ömürlü ve ağır çelik diskler ile aşmaya çalışmaktadır. Gerçek bir otobüs fren tertibatında farklı malzemelerden yapılmış disk fren rotor diskinin geçici termal ve yapısal analizi FEM tabanlı ANSYS yazılımı öğrenci lisansı yardımıyla frenleme koşulları altındaki termomekanik davranışını analiz etmektir. Disk freninde oluşan gerilme ve gerinimleri analiz etmek için bazı sınır şartları uygulandıktan sonra diskte meydana gelen deformasyon, kesme gerilmesi, elastik gerinim ve eşdeğer gerilme değerleri şekilleri alınmıştır. Tasarım açısından farklı malzemeler kullanılarak disk fren tertibatını dayanım karşılaştırması yapılmıştır.

Finite Element Thermo-Mechanical Analysis of Heavy Vehicle Brake Disc

Öz

Nowadays, there are very rapid developments especially in automobile technology. In buses and trucks, which are both automobiles and heavy-duty vehicles, the disc brake system is a system that slows down and stops the vehicle's wheel rotation. When braking to stop the vehicles, a heat is generated and the system can easily disperse because it is open to the atmosphere. Manufacturers try to overcome this situation with short-lived and heavy steel discs. Transient thermal and structural analysis of disc brake rotor disc made of different materials in a real bus brake assembly is to analyze the thermomechanical behavior under braking conditions with the help of FEM based ANSYS software student license. In order to analyze the stresses and strains occurring in the disc brake, after applying some boundary conditions, the deformation, shear stress, elastic strain and equivalent stress values of the disc were taken. The strength comparison of the disc brake system was made by using different materials in terms of design.
