Chromium Coated parts which are widely used inside and outside of a vehicle are exposed to different external conditions. Corrosive and thermal effects can be observed on the part due to rain, dust and sun. In this study, a finite element method is developed in order to anlyze the thermal deformations which may lead cracks on chromium coated parts, The layers of the coating are modelled seperately. The effects of the thickness of the layers and the geometric changes on the fracture were investigated.

Krom Kaplamalı Parçalarda Termal Çevrim Analizi

Öz

Araç içi ve dışında geniş kullanım alanına sahip krom kaplamalı parçalar, bulundukları konuma göre farklı dış etkilere maruz kalmaktadır. Yağmur, toz ve güneş nedeniyle parça üzerinde korozif ve termal etkiler görülmektedir. Bu çalışmada, krom kaplamalı plastik parçaların üzerinde sıcaklık nedeniyle oluşan çatlaklara neden olabilecek termal deformasyonların sonlu eleman yöntemiyle analiz edilebileceği bir yöntem geliştirilmiştir. Kaplamayı oluşturan katmanlar ayrı ayrı modellenip termal analiz yapılmıştır. Katmanların kalınlıklarının ve parça üzerindeki geometrik değişikliklerin termal yükler sonrası oluşan gerilme dağılımına etkisi incelenmiştir.
