Özet: Hydraulic excavator is a heavy-duty machine that is generally employed in constructional and mining works for digging, carrying and sometimes leveling of bulk materials. It consists of several components such as the engine house, boom, arm, bucket, swing bearing, carriage, etc. Excavators are designed to handle bulk materials that can vary in shape and form, from large quarry rocks to cohesive soils, abrasive ores or free flowing granules. These materials and their interaction with the machine parts have a strong effect on the equipment performance. Understanding how bulk materials will behave with equipment is critical to ensure an optimal design that combines strength and durability, with performance efficiency. In this paper, research was conducted to understand the effect of bulk material interactions on the excavator bucket. The excavator was designed with Autodesk Inventor software and simulated in an EDEM bulk material simulation environment, the results of the total pressures and compressive forces acting on the bucket were investigated in Ansys Mechanical to check for deformations and available stresses. As a result of the analyses, the bucket suffered small deformation and stresses with maximum recordings of 0.55145mm and 138.75MPa respectively. It has been found that these stresses and deformations do not seriously damage the bucket.
