In
this study, the effects of the ribs on the deformation of the plastic part were
investigated. In this context, four different rib parameters have been
selected, namely the rib thickness, the rib height, the rib angle and the
radius at the bottom of the feds. 5 different heights, 5 different thicknesses,
5 different radiuses and 3 different rib angles were used for designing of
plastic part and analyzing of the mechanical properties of the plastic part.
Resistance of the plastic part according to the identified parameters was
determined by analyzing with Ansys software. According to this study, the
increase in rib height reduces the deformation rate of plastic part by about
49%. In addition, was found that rib thickness reduce the amount of deformation
rate by 44%.

Polipropilen malzemeden üretilmiş plastik parçada federlerin deformasyon üzerindeki etkilerinin araştırılması

Öz

Bu
çalışmada, federlerin plastik parçanın deformasyonuna etkileri incelenmiştir.
Bu bağlamda, feder parametresi olarak feder kalınlığı, feder yüksekliği,
federin açısı ve federlerin dip kısmındaki yarıçapı olmak üzere dört farklı
feder parametresi belirlenmiştir. Plastik parçanın mekanik özeliklerini analiz
edebilmek 5 farklı yükseklik, 5 farklı kalınlık, 5 farklı yarıçap ve 3 farklı
feder açısı belirlenerek tasarım yapılmıştır. Plastik parçanın belirlenen
parametrelere göre mukavemeti Ansys yazılımı ile analiz yapılarak tespit edilmiştir.
Bu çalışmaya göre, feder yüksekliğinin artması deformasyon oranını yaklaşık %49
azaltmaktadır. Ayrıca, feder kalınlığı ise deformasyon miktarını %44 oranında
azalttığı tespit edilmiştir.
