In this study, the effects of ribs on the stresses formed in the polymer part were investigated. The angles of 3 different ribs, 5 different rib heights, 5 different rib thicknesses, and the bottom radius of 5 different ribs were determined as the rib parameter. The strength analysis of the part designed with these values was made in Ansys software. With the designed rib, it was determined that the lowest stress was 31.49 MPa and the stress ratio of the part decreased by 10% at the pressure applied from the A surface. It was determined that the lowest stress was 26.3 MPa under the applied pressure from the B surface and the stress ratio of the part decreased by 25%. It was determined that the lowest stress was 28.21 MPa under the applied pressure from the C surface, and the stress ratio of the part decreased by 18%. It was determined that the lowest stress was 21.57 MPa and the stress ratio of the part decreased by 39% at the pressure applied from the D surface.

Plastik Parçalarda Federin Gerilmeler Üzerindeki Etkilerinin Araştırılması

Öz

Bu çalışma, federlerin polimer parçada oluşan gerilmeler üzerine etkilerini incelenmiştir. Feder parametresi olarak birbirinden farklı 3 federin açısı, birbirinden farklı 5 feder yüksekliği, birbirinden farklı 5 feder kalınlığı, ve birbirinden farklı 5 federlerin dip yarıçapı belirlenmiştir. Bu değerlerle tasarımı yapılan parçanın mukavemet analizi Ansys yazılımında yapılmıştır. Tasarlanan feder ile A yüzeyinden uygulanan basınçta en düşük gerilme 31,49 MPa ve parçanın gerilme oranının %10 azaldığı tespit edildi. B yüzeyinden uygulanan basınçta en düşük gerilme 26.3 MPa ve parçanın gerilme oranının %25 azaldığı tespit edildi. C yüzeyinden uygulanan basınçta en düşük gerilme 28,21 MPa ve parçanın gerilme oranının %18 azaldığı tespit edildi. D yüzeyinden uygulanan basınçta en düşük gerilme 21,57 MPa ve parçanın gerilme oranının %39 azaldığı tespit edildi.
