Abstract
This thesis studies the concept of finite element method and its application to the Bucket attachment for excavator design. In fact, the purpose of this thesis was to find a new way for designing an excavator, which is more efficient from the economic and mechanical point of view. The present review provides brief information about the Bucket attachment for an excavator. The use of Hradox-400 material instead of Steel ASAI C 2010 in the Bucket Attachment for the Excavator can increase the volumetric capacity of the bucket and make it lighter. As the present mechanism used in Bucket attachment for excavator is subjected to torsional and bending stresses, so it is necessary to design a new mechanism. The finite element method was used to find out the optimized design solution. SOLIDWORKS 2013 Software was used for CAD design. Finite Element Methodology was used to find out dynamic fatigue failure of excavator arm mechanism design using SIMWISE 4D software for different material properties. Finite Element Methodology vi increased the productivity of Bucket attachment for excavator mechanism design, helped to conceptualize the product, reduced time required to design and analysis. The results of this thesis are stress; strain and displacement of the final geometry of the Hardox- 400 for arm and boom are lower than max stress and strain. In addition, the attach how can make the weight of the stick and boom lighter than steel. Although the costs of mechanical components made of Hardox-400 are more expensive than those made of steel, the results of this study clearly reveal the benefit of the increased capacity of the excavator outweighs the initial cost problem in the end.
