Modal Analysis of Rolling Element Bearing by Ansys

Rolling element bearings are important mechanical components used in sugar industry machinery because of their capability to support heavy radial and axial loads with minimum friction. Continuous operation of sugar mill equipment under severe working conditions leads to vibration, wear, and premature bearing failure. In this research work, a spherical roller bearing used in sugar industry machinery is analyzed using ANSYS-Workbench through Finite Element Method (FEM)-based modal analysis. A three-dimensional CAD model of bearing number 22218EK was developed in SolidWorks and imported into ANSYS Workbench for simulation. The bearing model was meshed and analyzed under fixed support boundary conditions. Material of 52100 Chrome Steel and Steel were assigned to different bearing components. The first six natural frequencies and corresponding mode shapes were obtained successfully. The results show that the bearing possesses stable dynamic characteristics and high structural stiffness. The study provides a theoretical basis for vibration prediction, resonance avoidance, and predictive maintenance of sugar industry machinery.
