Alüminyum alaşımlı jantların tasarım ve ağırlık optimizasyonu

Bu çalışmada A356 alaşımından üretilen binek araç jantlarının mekanik yükleme altında tasarım ve ağırlık optimizasyonu gerçekleştirilmiştir. Bu kapsamda seçilen bir jant modeli üzerinde geleneksel tasarım uygulamalarında mühendislik tecrübeleri ile gerçekleştirilen tasarım aşamalarında belirlenen ölçüler tasarım parametreleri olarak seçilmiştir. Tasarımda ANSYS Workbench’de “Sayısal Deney Tasarımı” yöntemi ile tasarım noktaları belirlenmiştir. “Cevap Yüzeyi Metodu” kullanılarak en iyi tasarım elde edilmiştir. Sonuç olarak jant ağırlığı ve deformasyonuna en çok etki eden parametreler belirlenmiş, tasarımın mekanik davranışı iyileştirilmiş ve daha hafif bir jant elde edilmiştir. Jantın geometrisi üzerinde gerçekleştirilen iyileştirme ile yorulma davranışı da iyileştirilmiştir.

Design and weight optimization of aluminum alloy wheels

In this study, design and weight optimization of passenger car wheels made of A356 alloy was conducted. In the course of the study a wheel was chosen and its dimensions that are generally used in the traditional design applications which applied by engineering experience were determined as design parameters. Design of Computational Experiments was used in ANSYS Workbench and optimum design was determined by Response Surface Method. As a result the most effective parameters on wheel weight and deformation were determined, the mechanical behavior of the wheel was improved and a lighter wheel was obtained. By improvements on wheel geometry, fatigue behavior was improved.
