Bu çalışmada, Ergiyik Depolayarak Modelleme (Fused Deposition Modelling - FDM) yöntemi ile üretilen kovan yatakların desteklediği milin titreşimlere karşı sönümleme kabiliyetleri deneysel olarak analiz edilmiştir. Çalışmada, PA12 (Nylon) filament malzeme kullanılarak farklı doldurma şekillerinde (Honeycomb, 3D Honeycomb, Gyroid, Hilbert curve, Archimed cords) ve doluluk oranlarında (% 10, 30 ve 50) toplam 30 adet kovan yatak üretilmiştir. Kovan yatakları analiz etmek için mil-yatak sisteminde aynı çalışma şartlarında 900 dev/dak mil dönme hızında deneysel çalışma gerçekleştirilmiş, kovan yatakların desteklerine bağlanan ivmeölçerler ile titreşim verileri toplanmıştır. Elde edilen sonuçlara göre, kovan yatakların titreşimi sönümleme kabiliyetlerinde önemli farklılıklar olduğu ve genel olarak doluluk oranları arttıkça titreşim genlik değerlerinin daha düşük olduğu görülmüştür.

Experimental Analysis of Vibration Damping Capabilities of Sleeve Bearings Printed Using FDM Method

Öz

In this study, vibration damping capabilities of sleeve bearing printed from PA12 (Nylon) filament material using Fused Deposition Modeling (FDM) method was experimentally analyzed. A total of a pair of 15 sleeve bearings samples for supporting rotating shaft were printed in different filling structures (Honeycomb, 3D Honeycomb, Gyroid, Hilbert curve, Archimed cords) with different occupancy rates (10, 30 and 50 %). The experiments were performed for rotating shaft running speed of 900 rpm. Vibration amplitude values were collected with accelerometers mounted on the sleeve bearing supports. The results showed that filling structures and occupancy rates had very important role in damping capabilities of sleeve bearings.
