Özet: This study addresses the modeling and static case analysis of carbon steel and alloy steel water pump impeller to inspect the deformation, stress, strain, vibrations and displacement. Pump impellers are mostly manufactured with stainless steel or mild steel in which its relative high density has led to an increase in corrosion resistance, weight and a low tensile strength. A brass, aluminium, titanium or plastic material can be deployed instead of carbon steel to enhance decomposition, durability and to create a lightweight pump impeller. For each of the material, the part geometry of the pump impeller and modeling is done separately using CATIA V5R20. Using FEM, the mesh visualization was done separately and in order to monitor the stress and deformation behavior, a force of 500N was used to make the von Mises stress values more significant and also to satisfy the static case. The applied force is being used to compute and display the von-misses stress, displacements, and deformation. The primary goal of this paper is to investigate for the most favorable material that is best suitable for manufacturing impeller. A structural analysis has been carried out to investigate for the best stress value between the materials as well as its displacement. This study also explains the modal analysis in demonstrating how quick either of the materials gets deformed with respect to its natural frequencies.
