Research on Optimization Design of Shot Blasting Machine Blade Based on Modal Analysis

The blade of shot blasting machine is taken as the research object. ABAQUS finite element software is used to analyze the blade modal of semi cylindrical end face and rectangular end face, analyze the blade failure causes from the angle of resonance and stress, and compare the data. The results show that there is no resonance between the two kinds of blades and the motor at rated power, there is stress concentration between the semi cylindrical blade and the center wheel, and the rectangular blade can reduce the stress concentration, which has reference significance for improving the reliability and prolonging the service life of the shot blasting machine.
