  "abstract": "<p>The goal of this study is analyzing and identifying the stresses on bolted rail joint due to the<br>\nwheel load to predict and minimize failures caused. The three dimensional model has been<br>\ndeveloped on modeling package of CATIAV5R16. In CATIAV5R16, different components of<br>\nwheel/rail assembly i.e. wheel, rail, joint, bars, nuts, bolts are created separately then all<br>\ncomponents are assembled, and create a complete model of wheel/rail assembly. Assembly<br>\nmodel has created in assemble workbench of CATIA after individual component of joint had<br>\ncreated on part work bench. After the assembly is accomplished on CATIA, it was imported in to<br>\nthe ANSYS v14.5 to analyze the stress caused by vertical load. The material properties of the rail<br>\nand wheel are assumed to be same. All the material properties and boundary conditions are being<br>\napplied to estimate fatigue stress. The analysis using the software ANSYS includes fatigue<br>\nstress, fatigue life, von miss stresses, shear stress and Equivalent elastic strain. These values have<br>\nbeen determined under the influence of axle load. The result obtained in this analysis is better<br>\nstress values for rail joint assembled by the modified geometry than the existing joint bar. During<br>\nthe rail joint analysis Joint between the sleepers needed more attention than other parts, to reduce<br>\nthe problem related to the rail joint.</p>",
