“…Dynamic models with impulse response include various factors such as nonuniform surface waviness [ 11 ], defects with different edge shapes [ 12 ], and defect size determination [ 13 ]. An overview of models is presented in [ 14 , 15 ]. The disadvantage of many models is that they do not consider the lubrication film or take into account its contact damping [ 16 ].…”

The impulse response of a rolling bearing and its principal component, the elasto-hydrodynamic lubrication film (EHDL), are analysed. When measuring the vibrations of bearings, we observed that the impulse response was mostly caused by defects (fatigue damage) on the raceways and/or rolling elements. However, this phenomenon can also occur in new defect-free roller bearings, where it is not commonly expected. This study presents an experiment that identifies the conditions of dynamic excitation for the impulse response of the EHDL, the source of which is not defects, but the EHDL itself. The EHDL responds in the form of impulses in case the velocity of its radial deformation is too fast. This is an unfavourable phenomenon that significantly shortens the service life of bearings. To analyse the dynamic excitation conditions, a testing bench at speeds up to 135,000 rpm with a flat belt drive was used. The testing bench enabled the formation of the so-called beat excitation from two harmonic excitation forces close in rotational frequency. The subject of this study is a defect-free high-speed double-row angular contact ball bearing used in the textile industry. We also present other physical conditions for the occurrence of undesired impulse responses that are caused by the EHDL.

“…The failure of a properly installed and lubricated bearing occurs in the form of surface fatigue cracks, such as spalls and pits [1]. In a ball bearing, spalls and pits often form on the contact surfaces between the raceways and balls.…”

To study the vibration mechanism of ball bearings with localized defects, a vibration model of a ball bearing based on the Hertzian contact stress distribution is proposed to predict the contact force and vibration response caused by a localized defect. The calculation of the ball-raceway contact force when the ball passes over the defect is key to establishing a defect vibration model. Hertzian contact theory indicates that the contact area between the ball and the raceway is an elliptical contact surface; therefore, a new approach is used to calculate the ball-raceway contact force in the defect area based on the stress distribution and the contact area. The relative motion between the inner ring, the outer ring, and the balls is considered in the proposed model, and the Runge-Kutta algorithm is used to solve the vibration equations. In addition, vibration experiments of a bearing with an outer ring defect under different loads are performed. The numerical signals and experimental signals are compared in the time and frequency domains, and good correspondence between the numerical and experimental results is observed. Comparisons between the traditional model and the proposed model reveal that the proposed model provides more reasonable results.

“…Niu et al [11] established a comprehensive dynamic model to explore the high-speed vibration response. In 2015, Singh et al [12] and Thalji et al [13] reviewed the current literatures on the faulty bearing modelling, respectively. Compared to the dynamic and defect model study of a defective bearings system, a huge amount papers focus on the feature extraction and diagnostic on a faulty bearing.…”

We intend to exploit the vibration status such as the resonance existed in a faulty bearing-rotor system on signal acquisition for diagnosis in this paper. We establish a symmetrical bearing-rotor-pedestal system to do the dynamic response analysis. The theoretical analysis indicates the resonances excited by the excitations can enhance the response in low-frequency range as well as the response in high-frequency range because the pulse energy produced by bearing defect increases under this situation. Finally, these conclusions are verified qualitatively by the experiment.
