Simulation and Static and Fatigue Analysis of Cross Bar of Moldboard Plough by Finite Element Method (FEM)

Frequent failures of mechanical components in machines and equipment due to exerted loads reveal the importance of optimizing or redesign the components. Practically, crossbar of moldboard plough is frequently failed in pin joints or deformed in support points. In this research, stress analysis of the crossbar was conducted by finite element method. After drawing the three-dimensional model in SolidWorks Software and transferring to ANSYS Software, the constraints and boundary conditions were applied on the model and the piece was loaded. Then the static and fatigue analyses were done on the model. To estimate the exerted forces on the crossbar, the maximum draft forces of Massey Ferguson 285 and 299 Tractor were considered. The results of static analysis showed the higher probability of failure at the left pin junction. The safety factor in fatigue analysis showed the higher probability of fatigue failure in left hole of crossbar. The safety factor in fatigue analysis of cross bar of moldboard plough during pulled by Massey Ferguson 285 and 299 Tractor was 1.67 and 1.677, respectively.
