EKLEMELİ İMALAT İÇİN TOPOLOJİ OPTİMİZASYONU: EL FRENİ MEKANİZMASI UYGULAMASI
Özet
Üretimi gerçekleştirilecek bir tasarımı, çok fonksiyonlu, mukavemeti yüksek ve hafif bir hale dönüştürmek tüm tasarımcı ve mühendislerin beklentisidir. Topoloji optimizasyonu, bu doğrultuda uygulanan optimizasyon tekniklerinden biridir. Topoloji optimizasyonu ile karmaşık geometriye sahip, kafesli yapıdaki parçaların elde edilmesi mümkündür. Yeni tasarlanan veya mevcutta var olan bir katı model üzerine kısıtlamalar getirilerek, kuvvet uygulanır. Optimizasyon işleminin tamamlanmasından sonra malzeme dağılımı optimize edilmiş, hafif ve çok fonksiyonlu ürünler elde edilebilir. Ancak karmaşık yapıdaki bu parçaların geleneksel imalat yöntemleri ile üretimi imkansızdır. Model üzerinde bir takım değişiklikler yapılması gerekir ve bu durum tasarımcılarının özgürlüğünü kısıtlar. Günümüzde kullanımı giderek artan eklemeli imalat teknolojileri ile karmaşık geometrideki parçalar tek işlem basamağında üretilebilmektedir. Bu teknolojilerin kullanımı, topoloji optimizasyonu sonucu elde edilen parçaların üretimini mümkün kılar. Bu çalışma kapsamında, fren braketinin topoloji optimizasyonu gerçekleştirilerek ideal forma ulaşması ve malzeme dağılımının düzenlemesiyle hafiflemesi sağlanmıştır. İşlem sonrası elde edilen parçanın eklemeli imalat yöntemlerinden biri olan Selective Laser Sintering (SLS) yöntemi ile destek parça kullanılmadan, modelin tamamlanmasından sonra ekstra bir işleme gerek olmaksızın üretimi planlanmıştır.

TOPOLOGY OPTMIZATION FOR ADDITIVE MANUFACTURING: AN APPLICATION ON HANDBRAKE MECHANISM
Abstract
It is in the expectation of all designers and engineers to turn a design that will be produced, multifunctional, with high strength and light weight. Topology optimization is one of the optimization techniques applied in this direction. With topology optimization, it is possible to obtain parts with complex geometries and lattice structures. The force is applied by imposing restrictions on a newly designed or existing solid model. After the optimization process is completed, the material distribution is optimized, light and multifunctional products can be obtained. However, it is impossible to produce these complex parts with conventional manufacturing methods. A number of modifications have to be made to the model and this restricts the freedom of designers. With the increasing use of additive manufacturing technologies, parts in complex geometry can be produced in a single process step. The use of these technologies makes it possible to produce parts obtained as a result of topology optimization. Within the scope of this study, it was ensured that the handbrake bracket was optimized with topology optimization and reached the ideal form and the material distribution was alleviated. Selective Laser Sintering (SLS) method, which is one of the additive manufacturing methods of the part obtained after the process, is planned to be produced without any additional parts after the completion of the model.
Keywords; Structural optimization, Topology optimization, Additive manufacturing technologies, Selective laser sintering (SLS).
