Balpeteği Sandviç Kompozitlerin Treyler Ön Panellerine Uygulanabilirliğinin Sonlu Elemanlar Analizi ile İncelemesi

Bu çalışmada, tenteli perdeli treyler ön panellerine balpeteği sandviç kompozitlerin uygulanabilirliği sonlu elemanlar analizi (FEA) ile incelenmiştir. Balpeteği sandviç yapılı kompozitlerden; polipropilen (PP) balpeteği, S320 çelik levha ve 3005 H19 alüminyum alaşımı balpeteği, 5457 H22 alüminyum levhalardan imal edilmiş iki farklı kompozit bu çalışmanın kapsamında değerlendirilmiştir. TS EN 12642 normunda belirtilen test standartları göz önüne alınarak statik analizler gerçekleştirilmiştir. Kompozit malzemelere uygulanan analizlerde gerilme dağılımı, toplam deformasyon ve gerinim enerjisi çıktıları değerlendirilmiştir. Analizler sonucunda, PP balpeteği kompozit ön panelde en yüksek gerilme değeri 2439 MPa, deplasman 68mm ve gerinim enerjisi 3108 mJ olarak elde edilmiştir. Alüminyum balpeteği kompozit ön panelde ise en yüksek gerilme değeri 391 MPa, deplasman değeri 29 mm ve gerinim enerjisi 286 mJ olarak bulunmuştur. Elde edilen veriler göz önüne alındığında, polipropilen balpeteği yapılı kompozit ön panel için gerekli özellikleri sağlayamadığı, alüminyum balpeteği yapılı kompozitlerin ise uygulanabilir olduğu sonucuna varılmıştır.

Investigation of the Applicability of Honeycomb Sandwich Composites to Trailer Front Panels by Finite Element Analysis

In this study, the feasibilty of honeycomb sandwich composites to curtainsider trailer bulkhead was investigated by finite element analysis (FEA). Honeycomb sandwich composites: two different composites made of polypropylene (PP) honeycomb, S320 steel skin and 3005 H19 aluminum alloy honeycomb, 5457 H22 aluminum skin were evaluated within the scope of this study. Static analyzes were carried out considering the test standards specified in the TS EN 12642 norm. Stress distribution, total deformation and strain energy outputs were evaluated in the analyzes applied to composite materials. As a result of the analysis, the highest stress value was obtained as 2439 MPa, displacement 68mm and strain energy 3108 mJ in the PP honeycomb composite front panel. In the aluminum honeycomb composite front panel, the highest stress value was found to be 391 MPa, the displacement value was 29 mm, and the strain energy was 286 mJ. Considering the data obtained, it was concluded that polypropylene honeycomb composite front panel could not provide the necessary properties, while aluminum honeycomb composites were applicable.
