This process include topology optimization analysis, size optimization analysis and finite element analysis. In this research, the structure combine main frame and swing arm. The design weight of the main frame structure is set to be less than 20.8 kg. The bending stiffness and the torsion stiffness of the main frame structure are design to be greater than 500 N/mm and,2000 N.m/deg, respectively. The design weight of the swing arm structure is set to be less than 8.5 kg. The bending stiffness, torsion stiffness and, lateral stiffness of the swing arm structure are design to be greater than 1000 N/mm,400 N.m/deg and,400 N/mm, respectively. In this research, the TOSCA optimization software is used for the lightweight analysis of the motorcycle structure. Build three dimensions elastic-plastic finite element models by using ABAQUS software. To analysis stiffness, strength and, fatigue life of the motorcycle structure. According to the lightweight analysis process. Main frame and swing arm weight are 11.1 and 8.3 kg, respectively. The bending stiffness and the torsion stiffness of the main frame are 534.8 N/mm and 2143 N.m/deg, respectively. The bending stiffness, torsion stiffness and, lateral stiffness of the swing arm are 1000 N/mm, 414.3 N.m/deg and,526 N/mm, respectively. When the spring stiffness values of the motorcycle rear suspension system design in this study are set to 15,30,45 and 60 N/mm for four different stiffness values. The fatigue life cycle of the frame structure is , , and , respectively. The result shows that the spring stiffness value of the rear suspension system has its influence on the fatigue life of the frame structure. When the spring stiffness reaches a fixed value. Continue increase the spring stiffness will only cause the suspension system lose the performance of the shock and reduce the fatigue life of the frame structure.
