: A deep groove ball bearing is a rotary element designed for supporting a radial as well as axial load, low friction, and widely used due to little noise and vibration which supports high rotational speeds. In this article, the author carried out a structural analysis (using FE Simulation) of a single row deep groove ball bearing for estimating contact stress and total deformation for three grades of materials viz. Silicon Nitride (Si3N4), 440C Stainless Steel, and AISI 4140 Alloy Steel. Under the scope of the study, modeling is done using Autodesk Platform and analyzed using ANSYS as an FEA tool. The natural boundary conditions were applied to estimate the fatigue life of bearings under standard operating conditions. The obtained results indicate Silicon nitride material was found to be more significant amongst all materials taken for considerations.

Modelling and Comparative Study for Deep Groove Ball Bearing Based on Structural Analysis using FE Simulation

Road transport is an important aspect of routine transportation. This paper describes the tie-down methodology for transportation container for safe transportation conditions comprises of applying known acceleration inputs (varying frequencies) to the given container and correlating the response on a virtual simulation model using FEA software. The required input for FEA is taken from Indian road conditions includes accelerations in lateral, longitudinal and vertical directions on the transportation container. Experimentation is done through multi-axis simulation table (MAST) is used for determination of acceleration factors using low-frequency excitation signals which are generally linked with transport vehicles. The results are compared with FEA results in order to develop a methodology for the prediction of acceleration factors on transportation container. The developed solution has been successfully tested on taking an industrial component and verified. The same may be used for prediction of the dynamic behavior of the industrial component.
