Bu çalışma, EYM (Eriyik Yığma Modelleme) yöntemiyle üretilen bal peteği yapısına sahip polimer kirişlerin titreşim sönümleme davranışını incelemektedir. Çalışmada, bal peteği dolgulu kiriş numuneleri farklı geometrik parametreler (cidar kalınlığı, hücre kenar uzunluğu, doluluk oranı) göz önünde bulundurularak üretilmiş ve bu parametrelerin titreşim karakteristiği üzerindeki etkileri analiz edilmiştir. Ayrıca, iç dolgu içermeyen (kabuk tipi) ve tam dolu kirişlerle karşılaştırmalar yapılarak bal peteği geometrisinin sönümleme performansına katkısı değerlendirilmiştir. Modal analizlerde çekiç-darbe testi ve ivmeölçer kullanılarak frekans yanıtı ve sönüm oranları elde edilmiştir. Sonlu elemanlar yöntemi ise üretim sürecinde oluşabilecek boyutsal hataların titreşim davranışı üzerindeki etkilerini belirlemek amacıyla kullanılmıştır. Elde edilen bulgular, bal peteği yapıların uygun geometrik tasarımıyla hafiflik sağlarken aynı zamanda titreşim sönümleme performansını artırabileceğini göstermektedir. Bu sonuçlar, özellikle hafif ve yüksek performanslı pasif titreşim kontrol elemanlarının geliştirilmesine yönelik tasarımlar için yol gösterici niteliktedir.
