碩士 === 雲林科技大學 === 機械工程系碩士班 === 96 === In this research, two topics are studied: (1) the simulation of radial test for aluminum wheel and (2) simulation analysis of impact test for aluminum wheel. The finite element software ANSYS Workbench is used to perform the simulation of radial test for aluminum wheel, also the fatigue strength is modified by the modification factor based on the geometrical shape and surface finish of the wheel location. The simulation results can predict a reasonable fatigue life of aluminum wheel and compared with radial tests to verify the accuracy of the finite element model. In the second topic, the finite element software ABAQUS is used to perform the simulation of impact test for aluminum wheel. The simulated results are compared with strain measurement by strain gages to verify the accuracy of the element model. The prediction of a wheel failure is based on the condition that fracture will occur if the maximum strain energy density of the wheel during the impact test exceeds the total plastic work of the wheel material from tensile test.
