Stress analysis and improvement of boom and arm of an excavator

The aim of this study is to analyze boom and arm of excavator and to improve the stresses depending on forces. Besides these stresses remain below the limit values as desires, it is aimed to provide using optimum material. Primarily force analyses is finished. Then the front attachment is simulated and modeled according to critical position of machine. The improvement is applied according to the results. Finite element method (FEM) is applied to the engineering problem as a numerical solution methods. Simxpert software program is used in finite element analysis.
