Abstract

The paper presents the optimization process of bucket shape of an excavator based on strength analysis. The analysis was based on a three-dimensional model of bucket construction using finite element method (FEM). Application of this method allowed to modify the structure, which resulted in the reduction of stresses in the most loaded areas of the construction. The presented analysis proved to be a simple and relatively inexpensive way of optimizing complex mechanical structures at the design stage.
