Abstract:

Excavators are primarily be used to excavate below the natural ground, on which the Machine also rests. Due to severe working conditions, excavator parts are subjected to high wear and tear. For better results, the excavator mechanism should work efficiently and effectively in unpredictable working conditions. In this work, the reference of a backhoe machine failure case has been taken for its analysis. At first, all the relevant data concerning the Machine has been collected and tabulated, further based on the data collection, a 3D-CAD model of the machine components is generated in the 3D mechanical design package software PRO-E wildfire V 5.0, which is further analyzed in the PRO-E Mechanica module of the same for static, kinematic and dynamic condition, to know the behavior of the connections between the components of the Machine in sustaining the forces/ stresses generated in carrying out the required activity with enough strength, which results in better design optimization. Further, the Finite Element Analysis (FEA) of the boom (Boom) has been carried out to evaluate the boom's stresses and deflection to qualify the same with the standards for the system's fatigue life. Hence based on optimum findings [Factor of Safety (FOS)] from the analysis, we can predict the approximate machine life in the considered working conditions as per the ASME standards.
