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.

Alüminyum alaþýmlý jantlarýn tasarým ve aðýrlýk optimizasyonu

Bu çalýþmada A356 alaþýmýndan üretilen binek araç jantlarýnýn mekanik yükleme altýnda tasarým ve aðýrlýk optimizasyonu gerçekleþtirilmiþtir. Bu kapsamda seçilen bir jant modeli üzerinde geleneksel tasarým uygulamalarýnda mühendislik tecrübeleri ile gerçekleþtirilen tasarým aþamalarýnda belirlenen ölçüler tasarým parametreleri olarak seçilmiþtir. Tasarýmda ANSYS Workbench’de “Sayýsal Deney Tasarýmý” yöntemi ile tasarým noktalarý belirlenmiþtir. “Cevap Yüzeyi Metodu” kullanýlarak en iyi tasarým elde edilmiþtir. Sonuç olarak jant aðýrlýðý ve deformasyonuna en çok etki eden parametreler belirlenmiþ, tasarýmýn mekanik davranýþý iyileþtirilmiþ ve daha hafif bir jant elde edilmiþtir. Jantýn geometrisi üzerinde gerçekleþtirilen iyileþtirme ile yorulma davranýþý da iyileþtirilmiþtir.
