Experimental Vibration Investigation of Roller Element Bearing With Combined Faults Using Surface Response Methodology

The empirical and mathematical approach is presented in the present paper for multiple distributed and localized flaws analyses in the shaft-rotor-bearing arrangement. These flaws in the combination of the inner raceway, outer raceway, and roller are measured for the analysis. To comprehend their relevance and how they affect the vibration response for the shaft-rotor-bearing mechanism, speed, load, and flaws were regarded to be the crucial process factors in this investigation. The full factorial method was considered for experimentation, and the experiment was done with the design of experiments (DOE) methodology. The outcomes of the vibration response trials are quantified as root-mean-square (RMS) values for interpretation. To determine the relationship between the effects of changing process parameters on the response of vibrations, surface response methodology (SRM) is applied. DOE is used to examine the shaft-rotor-bearing test arrangement, which is employed for exploration. In the present research, it is established how combined parametric effect analysis predicts faults in the shaft-rotor-bearing system and how it affects DOE and RSM.
