Today, the excavator arm, which is one of the important parts of excavators that are widely used in many areas, especially in the construction sector, provides the movement of the excavator's bucket. Excavator arms are produced in different sizes and shapes according to the usage areas of excavators. In this study, a solid model of a sample excavator arm was created using the SolidWorks design program and the values of the forces that may occur depending on the load lifted on the excavator arm were calculated if the excavator lifted a load of 1000 kg. Matlab and Gauss Elimination Method were used to find the force values. In line with the force values obtained, linear static analysis and fatigue analysis were applied to the excavator arm, whose weight was reduced by topology optimization and shape optimization. According to the results obtained from the fatigue analysis, the areas where the fatigue limit was exceeded on the excavator arm were determined and it was aimed to create a more durable and safer design for the excavator arm in terms of damage and life. While creating the design, attention was paid to the weight of the excavator arm and the maximum stress and maximum displacement values on the excavator arm. HyperMesh program was used for fatigue analysis and linear static analysis.
