Abstract

An AutoBlast machine or the more renown as the Centrifugal Blasting Machines,is a machine used in surface finish process of metal.Inside the blasting machines is equipped with a rotating wheel housing a sets of blades powered by electrical motor.The heavy rotating wheel is feed with abrasive media called grits that is then being shot out in high velocity propelling the grits on to the surface of any metal test piece.Due to the high rotating frequency of the wheel and the contact between the blade and the grits creates stress on the wheel component.This project is proposed to analyze the fatigue life of the wheel component based on the original materials used to manufacture it.Focus on the fatigue study regarding the wheel component,the remote force approach is applied to simulation.Remote force approach helps in simulated force distribution as the blade component is set as a rigid body.This method help in studying the stress and deformation of a contact body which is the wheel component.This project mainly uses the Ansys software as the finite element analysis tools in order to determine the maximum stress from the static structural analysis.This approach helps in locating the high stress region within the wheel component that can be the factor that lead the component to fail.The static structural simulation give the results of maximum stress registered at a sharp edge within the design with the stress magnitudes of 103.17 MPa.Meanwhile,the fatigue analysis is done based on the static structural results to find out the total life cycles of the component.The maximum life cycle of the wheel component obtained to be around 10 cycles,with the mean stress amplitude of 61.882 MPa.Based on the results obtained,the data is correlates with the real life operation specifications to give out the maximum life of the wheel component to be 2 years and 104 days.
