Design Optimization and Fatigue Analysis of Turgo Impulse Blade

Abstract

This paper emphasizes on the fatigue analysis of 500W turgo impulse turbine blade by using numerical approach method to improve the quality of turbine blade. Solidwork software is used for designing turbine blade and ANSYS 16.2 ncode design life software is used for simulation fatigue. Life, damage, total deformation and Von Mises stresses are analyzed to estimate the stresses occurring places where turbine blade can bear for better design results. Stainless steel, aluminium, and gray cast iron are applied for bucket materials to measure the better result for turbine. Blade design is developed by hand calculation to get better efficiency and turbine performance.
