This study aims at the structural analysis of vibration and fatigue according to the tie rod configuration. The maximum displacement amplitude is happened at 156Hz by harmonic vibration analysis, this tie rod model can be broken as the weakest state. Among the cases of nonuniform fatigue loads, "SAE bracket history" with the severest change of load becomes most unstable but "Sine wave" becomes most stable. In case of "Sine wave" with the average stress of 0MPa and the amplitude stress of 570MPa, the possibility of maximum damage becomes 70%. This stress state can be shown with 140 times more than the damage possibility of "SAE bracket history" or "SAE transmission". The structural result of this study can be effectively utilized with the design on tie rod by investigating prevention and durability against its damage.
