The vibration response of ball bearing with local defect is closely associated with its lubrication condition. The previous bearing dynamic models were mainly established based on the idealised lubrication conditions, which may not uncover the influence of thermal effect of lubricant on vibration characteristics of defective bearing. This paper presented the influence of thermal effect on elastohydrodynamic lubrication (EHL) performances of ball bearing and the vibration characteristics of defective bearing under thermal EHL. Considering the point contact thermal EHL and the time-varying displacement excitation, a dynamic model of ball bearing with a localised defect on outer raceway was developed. The model was validated by the experimental results. Compared with isothermal EHL, the simulation results with thermal EHL reveal larger pressure and thinner film thickness in the ball-raceway contact interface. Meanwhile, the rotating speed and radial load have significant effects on the thermal EHL performance of ball bearing. The effects of three contact conditions (dry friction, isothermal and thermal EHL) on vibration amplitude of defective bearing in frequency domain are discussed. The results show that the lubricant could improve the vibration of defective bearing, whereas the addition of thermal effect of EHL could increase the vibration amplitude and deteriorate the lubricating performance. The model is beneficial to the bearing model optimisation and the rational selection of lubricants.

The numerical model is developed to study the vibration response due to the localized defect of ball bearing in rotating machinery. In order to simulate the dynamic response, the equations of motions are developed based on the rotor-bearing system where two identical rotors mounted on symmetric flexible shaft and supported by ball bearings are considered in this model. The presence of defect is introduced on a bearing outer raceway and lubrication effect between bearing components is also included. The numerical results are obtained by applying Runge–Kutta method to solve governing equations of motions. It has been observed that the vibration spectrum of the ball pass frequency outer race and its harmonics for the defect bearing is relatively higher than the good one. Moreover, this dynamic model can effectively enhance the understanding of vibration responses for good and defective bearing.

In this paper, the dynamic behavior of rolling element bearings with localized faults on the inner and outer rings is investigated. A nonlinear mathematical model is developed with five degrees of freedom considering rotor unbalance. In this bearing model, the nonlinearity is caused by the Hertzian contact forces and the radial internal clearance. The fourth-order Runge–Kutta technique is used to solve the coupled nonlinear equations of motion numerically. Nonlinear vibration response of the rotor and bearing housing can be obtained in both time and frequency domains. An experimental verification of the numerical model is presented where experimental measurements for defective ball bearings are compared with the numerical results. Envelope spectra of the numerical results show similar behavior to that of the measured experimental signals. A parametric analysis is conducted to investigate the effect of system parameters on the nonlinear dynamic response using time waveforms, orbit plots, frequency spectra and bifurcation diagrams. The presented results demonstrate that the dynamic response shows periodic, quasi-periodic and chaotic motions because of varying rotational speeds and defect width. The proposed model contributes toward improved design and better health monitoring of bearings in practice.
