Abstract

The goal of this study is to examine the effects of fiber type and number of layers on modal analysis of
laminated composite plates using finite element and Taguchi methods. Modal analysis was carried out by
finite element software ANSYS in accordance with L9 orthogonal array which has two control factors such
as fiber types and number of layers. Optimal levels of fiber types and number of layers were determined
using analysis of Signal-to-Noise ratio, while importance levels and percentage effects of control factors
were performed using analysis of variance at 95% confidence level. According to results obtained from this
study, the maximum fundamental natural frequency value was calculated using boron-fiber-reinforced
laminated composite plates with three layers. Numerical and statistical results obtained from this study can
be useful to select the appropriate fiber types and number of layers for laminated composite plates.

Tabakalı kompozit plakaların modal analizi üzerinde tabakaların fiber tipi ve sayısının etkisi

Abstract

Bu çalışmanın amacı, sonlu elemanlar ve Taguchi yöntemleri kullanılarak tabakalı kompozit plakaların
modal analizinde fiber tipi ve katman sayısının etkilerini incelemektir. Modal analiz, fiber türleri ve katman
sayısı gibi iki kontrol faktörüne sahip L9 ortogonal diziye uygun olarak sonlu elemanlar yazılımı ANSYS ile
gerçekleştirilmiştir. Sinyal-Gürültü oranı analizi kullanılarak optimum lif türleri ve katman sayısı belirlenirken
kontrol faktörlerin önem seviyeleri ve yüzde etkileri %95 güven düzeyinde varyans analizi kullanılarak
gerçekleştirilmiştir. Bu çalışmadan elde edilen sonuçlara göre, maksimum serbest titreşim değeri üç
katmanlı bor lifi takviyeli tabakalı kompozit plakalar kullanılarak hesaplanmıştır. Bu çalışmadan elde edilen
sayısal ve istatistiksel sonuçlar, tabakalı kompozit plakalar için uygun fiber tiplerini ve katman sayısını
seçmek için faydalı olabilir.
