DESIGN AND STRUCTURAL-BASED CLASSIFICATION OF DIFFERENT LATTICE STRUCTURES VIA IMPLICIT MODELING METHOD

Öz

In this study, lattice structures from different categories available in the nTop software were parametrically modeled by integrating them into a fixed control volume, and their static and modal analyses were performed. Thanks to nTop’s field-based modeling approach, free-form geometries were generated with high accuracy, and a reusable workflow was developed for the analyses. A total of 23 different lattice models were designed and analyzed under identical conditions, and their mass, solid volume ratio, stiffness, and displacement behaviors were compared. The findings reveal significant differences among lattice structures in terms of mass, stiffness, and vibration characteristics. In this context, the study highlights the advantages of different lattice types in engineering applications with respect to lightweight design, durability, and dynamic performance, thereby providing guidance to researchers and designers during the preliminary design stage.

Öz

Bu çalışmada, nTop yazılımı içerisinde sunulan farklı kategorideki kafes yapılar sabit bir kontrol hacmi içerisine entegre edilerek parametrik olarak modellenmiş ve statik ile modal analizleri gerçekleştirilmiştir. nTop’un alan temsiline dayalı modelleme yaklaşımı sayesinde serbest geometriler yüksek doğrulukla oluşturulmuş ve analizler için yeniden kullanılabilir bir süreç geliştirilmiştir. Çalışmada, 23 farklı kafes modeli tasarlanmış ve her biri aynı koşullar altında analiz edilerek kütle, katı hacim oranı, rijitlik ve yer değiştirme davranışları açısından karşılaştırılmıştır. Elde edilen bulgular, kafes yapıların kütle, rijitlik ve titreşim özellikleri arasında önemli farklar ortaya koyduğunu göstermektedir. Bu kapsamda çalışma, farklı kafes tiplerinin mühendislik uygulamalarında hafiflik, dayanıklılık ve dinamik performans açısından sunduğu avantajları genel hatlarıyla ortaya koymakta ve ön tasarım aşamasında araştırmacılar ile tasarımcılara yol göstermektedir.
