In this study, the influence of layer arrangements on
free vibration behavior of beams which have layers in the axial direction is investigated
by using finite element program (ANSYS) according to Timoshenko Beam
Theory.  Each layer has different systems
such as Aluminum/Alumina, Aluminum/Zirconia and Aluminum/Nickel. Layer arrangements
are conducted using the L9 orthogonal array in Taguchi Method. In order to obtain
the sorting order of optimum layers, Taguchi Method and optimum layer
combination are utilized. Analysis of Variance (ANOVA) is used to carry out the
significant layers and percentage of contribution on the responses. According
to the results, the most effective parameters on the responses are obtained for
Aluminum/Alumina with 67.94%, Aluminum/Nickel with 31.08% and Aluminum/Zirconia
with 0.95%, respectively. Fundamental frequency values increase with the
increasing Aluminum/Alumina and Aluminum/Zirconia contents and decrease with Aluminum/Nickel
content in layers.

Bu çalışmada eksenel yönde tabakalara sahip kirişlerin
serbest titreşim davranışı üzerinde tabaka sıralamalarının etkisi Timoshenko
kiriş teorisine göre sonlu elemanlar programı (ANSYS) kullanılarak
incelenmiştir. Her tabaka Alüminyum/Alüminyum oksit,  Alüminyum/Zirkonyum ve Alüminyum/Nikel gibi
farklı sistemlere sahiptir. Tabaka sıralamaları Taguchi Metodunda L9 orthogonal
dizi kullanılarak yürütülmüştür. Optimum tabakaların sıralamasını elde
edebilmek için Taguchi Metodu ve optimum tabaka kombinasyonu kullanıldı.
Yanıtlar üzerinde önemli tabakaları ve katkı yüzdelerini gerçekleştirebilmek
için Varyans Analizi (ANOVA) kullanıldı. Sonuçlara göre yanıtlar üzerinde en
etkili parametreler sırasıyla %67.94 ile Alüminyum/Alüminyum oksit, %31.08 ile
Alüminyum/Nikel ve %0.95 ile Alüminyum/Zirkonyum için elde eddilmiştir. Temel
frekans değerleri tabakalardaki Alüminyum/Alüminyum oksit ve Alüminyum/Zirkonyum
içeriklerinin artmasıyla artmış ve Alüminyum/Nikel içeriğinin artması ile
azalmıştır.
