Topoloji Optimizasyonu Kullanılarak Etkili Karık Açma Montaj Braketinin Tasarımı ve Geliştirilmesi

Öz

Günümüz dünyasında, tarım makinelerinde mühendislik teknolojisi ve araçları kullanılarak yapısal ve tasarımsal iyileştirmeler yapılması hayati önem taşımaktadır. Topoloji optimizasyonu ve Sonlu Elemanlar Analizi (FEA) yöntemleri gibi mühendislik araçları kullanılarak maliyet etkin, yapısal olarak güvenli ve üretimi kolay bileşenler ve parçalar oluşturmak mümkündür. Bu çalışmada, rijitliği artırarak, ağırlığı azaltarak ve oluşan gerilmeleri optimize ederek karık açma makinesinin montaj braketi için bir yapı oluşturmayı amaçlanmıştır. Ön yapı tasarımı oluşturulmuş ve oluşan gerilmeleri gözlemlemek için FEA gerçekleştirilmiştir. Daha sonra aşırı ağırlıkları azaltmak ve nihai yapıyı oluşturmak için topoloji optimizasyonu uygulanmıştır. FEA ve yorulma analizi, optimize edilmiş yapıların mukavemetini kontrol etmek ve doğrulamak için yeni optimize edilmiş yapıya uygulanmıştır. Sonuçlardan ortalama ağırlığın %13,5 oranında azaldığı gözlemlenmiştir. Ayrıca, optimizasyonun yapısal stabilite ve mukavemeti korurken daha iyi üretilebilirlik ve maliyet verimliliği sağlayabileceği sonucuna varılmıştır.

Design and Development of Effective Furrower Mounting Bracket Using Topology Optimization

Abstract

Structural and design improvements on the agricultural machinery using the engineering technology and tools are crucial in today world. It is possible to create the cost effective, structurally safe, and easy to manufacture components and parts using engineering tools such as topology optimization and Finite Element Analysis (FEA) methods. In this study it was aimed to create an optimized structure for the agricultural mounting bracket of the furrower. For those purposes, preliminary structure design was created, and FEA was conducted to observe the occurred stresses, deformations and total mass. Then topology optimization was conducted to reduce the excessive weights. The FEA and fatigue analysis were applied to the new optimized structure to check and validate the strength. It was observed from the results that the weight was reduced by 13.5%. The occurred stresses and deformations values were found as almost same 199,0 MPa with the preliminary structure. From all obtained results it was concluded that the mounting bracket was structurally optimized. It had similar structural strength with reduced weight.
