| dc.description.abstract | The goal of this study is analyzing and identifying the stresses on E-clamp due to the wheel load to predict and minimize failures caused. This study covers the stress and failure caused by the wheel load. Under normal track and load conditions, E-clamp fail due to high cycle fatigue. The 3D model has done on modeling package of CATIAV5R19. In CATIAV5R19, different components of wheel/rail assembly i.e. wheel, rail, E-clamp, bolt, nuts, rail pad are created separately then all components are assembled, and create a complete model of wheel/rail assembly. Assembly model has created in assemble workbench of CATIA after individual component of joint had created on part work bench. After the assembly is accomplished on CATIA, it was imported in to the ANSYS v14.0 to analyze the stress caused by vertical load. The meshing type for this research is medium size meshing. All the material properties are being applied. During the analysis of wheel/rail contact in ANSYS software, the parameters have been used wheel load angular and simulation result is obtained. The analysis includes fatigue stress von miss stresses, shear stress and Equivalent elastic strain and fatigue life. These values have been determined under the influence of wheel load. The result obtained in this analysis is less and better stress values for E-clamp by the modified geometry. This paper recommends that during the analysis of E-clamp that the new geometry E-clamp is better than the existing. For the similar problem engineers can develop the solutions by modification of the geometry of rail fastening component parts. | en_US |
