Abstract—This study examines the dynamic behavior of the roller bearing used in wagon tippler. In this work various mode shapes and their frequencies accordingly has been investigated for the bearing without any wear, i.e., notch, scratch, cut, roughness. Then after, bearing with a definite defect of particular geometry has been created and various modes and frequency of that bearing has been calculated. A comparative study is also presented between both of the cases. A bearing is the most important element of any machine or equipment and various types of failures may be occurring in the same and wear and tear is one of them. Hence, this study will be useful to investigate the behaviour of bearing after locating a defect and this study also provide the safety features against the catastrophic failures of bearings. This work has been accomplished with FEM methodology and Ansys tool.
