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 on the basis of 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 analysed in the PRO-E Mechanica module of the same for static, kinematic and dynamic condition, to know the behaviour of the connections between the components of the machine in sustaining the forces/ stresses generated in carry 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 stresses and deflection of the boom to qualify the same with the standards for the fatigue life of the system. Hence on the basis of 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.
