Load Distribution Measurement for Different Defect Sizes Using Nonlinear Vibration Analysis in Deep Groove Ball Bearing

The deep groove ball bearing system local defect is investigated using a vibration model proposed in this paper. The model accounts for the masses of the housing, shaft, races, balls, damping, and race faults. The model proposes a piecewise response function that depends on the ratio of the defect size to the ball size. Analysis and discussion have been conducted on the impact of various defect sizes on measured load distribution. This mathematical model is solved using MATLAB and vibration responses are simulated for the bearing system. Experiments have been carried out, and the findings have been compared with simulation results to validate the simulation results. The comparison demonstrates that the features depicted in the simulated and experimental data are in agreement.
