Design and Analysis of Stress in Mixed Flow Impeller Blade Using Ansys

A static analysis of two different blades which are of trapezoidal shape and inlet inclined has been done in ANSYS software in order to find the stress distribution on different material. The materials that have been chosen for the study are titanium, stainless steel, Copper and bronze because they are widely used in area of fluid machinery. Then a comparison of von-Mises stress distribution for all the four materials has been done. To perform this work, ANSYS static structure analysis was used. The blade model was designed in ANSYS workbench. In this study one end of blade was fixed and force has been applied on the surface of blade, the see was used as boundary condition. The stress was measured at different value of forces and results are obtained. It has been observed that trapezoidal blade of stainless steel subjected to maximum stress and inlet inclined blade of stainless steel subjected to minimum stress. This work was further proceeding to find out the deformation in both cases of blade for all these four materials and then compared the results obtained from the analysis. It has been found that trapezoidal stainless-steel blade was subjected to maximum deformation.
