dc.description.abstractThe goal of this study is analyzing the fatigue on welded rail joint due to the wheel load and after to evaluate the fatigue life. The three dimensional model has been developed on modeling package of CATIAV5R19. In CATIAV5R19, different components of welded rail joint assembly i.e. rail, rail weld, sleepers are created separately then all components are assembled, and create a complete model of welded rail joint assembly. Assembly model has created in assemble workbench of CATIA after individual component of welding joint had created on part work bench. After the assembly is accomplished on CATIA, it was imported in to the ANSYS v15 to analyze the fatigue caused by vertical load. All the material properties and boundary conditions are being applied to estimate fatigue stress. The analysis using the software ANSYS includes fatigue stress, fatigue life, von miss stresses, shear stress and Normal strain. These values have been determined under the influence of the vertical load. From ANSYS software simulation result, if we compare the yield strength to the maximum equivalent stress, the yield strength is higher than the maximum equivalent stress. That proves that the welded joint can resist to the stress because of is strengthens. Then the survival probability of the fatigue life is 97, 5%.en_US
