Özet
Dövme, haddeleme ve bombeleme, demiryolu tekerleklerini üretmek için kullanilan özel sicak sekillendirme prosedürüdür. Sürekli gelisen teknoloji nedeniyle, demiryolu vagonlari ve lokomotifleri güvenlik ve hiz gereksinimlerini karsilamak için tekerlekler kullanan çesitli tasarimlara sahiptir. Sonuç olarak, bir demiryolu tekerlegi üreticisinin rekabetçi bir pazarda geçerliligini sürdürebilmesi için çok çesitli tasarimlara sahip demiryolu tekerlekleri üretme yetenegine sahip olmasi gerekir. Yeni bir tekerlek üretmek için, üreticinin tekerlegin yeni tasarimina uygun yeni kaliplar olusturmasi gerekir. Tasarim asamasinda, demiryolu tekerlegi sekillendirmenin olasi sonuçlarini tahmin etmek için bir simülasyon modeli kullanilmalidir. Demiryolu tekerlekleri sekillendirmenin en karmasik asamasi, tekerlek haddeleme sürecidir. Demiryolu tekerlegi haddelemesi, dövme demiryolu tekerleginin belirli bir sekil vermek için ayni anda bes silindir tarafindan islenmesidir.Bu çalismada, demiryolu tekerleklerinin üretim süreci ayrintili olarak incelenecek ve yeni tasarimlarin nasil olusturulacagina dair yöntemler ele alinacaktir. Ayrica, simülasyon modelleri kullanarak tekerlek sekillendirme süreçlerinin tahmin edilmesi ve haddeleme sürecinin optimizasyonu üzerinde durulacaktir. Tez, derleme formatinda sunulmus olup, süreçlerin degerlendirilmesi için ramak kala olay analizi ve balik kilçigi diyagrami kullanilacaktir.
Forging, rolling and crowning are specific hot forming procedures used to produce railway wheels. Due to the ever-evolving technology, railway wagons and locomotives have various designs using wheels to meet safety and speed requirements. As a result, a railway wheel manufacturer must have the ability to produce railway wheels with a wide variety of designs in order to maintain its validity in a competitive market. In order to produce a new wheel, the manufacturer must create new molds suitable for the new design of the wheel.A simulation model should be used in the design phase to predict the possible results of railway wheel shaping. The most complex stage of railway wheel shaping is the wheel rolling process. Railway wheel rolling is the simultaneous processing of the forged railway wheel by five rollers to give it a certain shape.In this study, the manufacturing process of railway wheels will be examined in detail and methods on how to create new designs will be discussed. In addition, the prediction of wheel shaping processes using simulation models and the optimization of the rolling process will be emphasized. The thesis is presented in a compilation format, and near-miss event analysis and fishbone diagram will be used to evaluate the processes.
