Abstract

The excavator bucket is one of the most critical components in excavation work, requiring both high strength and efficient weight. This study aims to optimize the design of the Komatsu PC 200 excavator bucket using the Finite Element Method (FEM) to enhance structural safety factors and efficiency. The optimization process involves replacing the bucket body material from AISI 4140 to AISI 4640, and the teeth material from regular steel to HARDOX 500, which has a higher yield strength. The initial simulation results show a maximum stress of 103,29 MPa, a deformation of 7,034 mm, and a safety factor of 7,03. After optimization, the maximum stress increases to 118,34 MPa, deformation to 6,684 mm, and the safety factor significantly improves to 2,763. These results indicate that the new design can withstand greater working loads with a lighter weight, providing better and structurally safer performance. This optimization demonstrates that proper material selection and accurate numerical analysis can significantly enhance the overall performance of an excavator bucket.
