Abstract

Bu çalışmada, kalibreler tasarlanmış ve gemi
yapılarında kullanılan düşük karbon-mikro alaşımlı çelik ile asimetrik bir
profil elde etmek için sonlu elemanlar metoduna dayanan Simufact Forming
simülasyon aracı kullanılarak kontrollü haddeleme simülasyonları gerçekleştirilmiştir.
Üretim kusurlarının ortadan kaldırılması, gerilme-gerinim eğrileri, merdanelere
etki eden kuvvetler ve merdanelerin giriş ve çıkışlarındaki tork
gereksinimlerinin sağlanması için simülasyon yardımlı imalat çalışmaları yapılmıştır.
Nihai ürünün mekanik özelliklerini iyileştirmek için üretim parametrelerinin
optimizasyon çalışmaları gerçekleştirilmiştir. Simülasyon destekli
faaliyetlerden elde edilen üretim parametrelerinin prototip üretiminde kullanılması
ve asimetrik profilin mekanik özelliklerinin geliştirilmesi sağlanarak elde
edilen üretim numunelerine mekanik testler ve metalurjik testler uygulanmıştır.

Abstract

: In this study, roll-pass designs were designed and controlled rolling simulations were realized by using of Simufact Forming simulation tool based on finite element method for acquiring an asymmetrical profile with low carbon- micro alloyed steel used in ship buildings. Simulation aided manufacturing studies have been realized for eliminating the manufacturing defects and obtaining stress-strain curves, forces acting on the rollers and torque requirements at the inlets and the outlets of the rolling stands. Optimization studies of the production parameters to improve the final product mechanical properties. Mechanical tests and metallurgical tests have been applied to the production samples obtained by ensuring that the production parameters obtained in simulated support activities are used in prototype productions and the improvement of the mechanical properties of the profile with asymmetric section is provided.
