“…In this study, a mathematical model was used for the study of the effect of clearance, waviness, preloading and radial forces on non-linear stability as well as for the study of rotor system vibrations at high speeds. On the other hand, Tomović et al [3] pointed out that the specific design of a bearing has a significant influence on its dynamic behaviour. In their study, they defined a new model of vibrations of a rigid rotor supported by ball bearings.…”

This paper presents the development of a methodology for calculating radial ball bearing vibrations. First, analytical and numerical models were developed and then, the obtained results were experimentally verified. In the experiment, a test rig for a dynamic testing of bearings subjected to an external load was used. Special attention was paid to the analysis of the total bearing deformations and stiffness, being the main parameters that define the dynamic behaviour of a bearing. In order to determine total deformations of a ball bearing as an assembly, a finite element model of the bearing was developed. The results obtained from the new methodology for a particular ball bearing type have been verified by experimental results. The obtained correlations of the experimental and the numerical results are about 2.5%. Based on the calculations and the experimental testing of the chosen ball bearing type, under conditions of a variable radial load, the analysis of the influence of the radial load on the dynamic behaviour of a ball bearing was performed. The analysis of the obtained results showed that the vibration amplitude increases with a similar multiple factor as loads increase.

The rolling element bearings are the integral components of the rotor shaft system. The failure of bearing can lead to catastrophic consequences. Toreduce the chances of failure in bearing, researchers have studied the dynamic and transient behavior of the mating bodies for the structural and vibrationanalysis. Various techniques were implemented and enough literature is available for the different conditions. In this review, various bearing rotor frameworks with different loading and fault condition were summarized. Moreover, different methods and techniques have increased the early prediction of the fault. Techniques like F. E. A proves to be promising tools to carry out the systematic dynamic behavior of the rotor-shaft system.

Simple vibration-based metrics are, in many cases, insufficient to diagnose machine tool spindle condition. These metrics couple defect-based motion with spindle dynamics; diagnostics should be defect-driven. A new method and spindle condition estimation device (SCED) were developed to acquire data and to separate system dynamics from defect geometry. Based on this method, a spindle condition metric relying only on defect geometry is proposed. Application of the SCED on various milling and turning spindles shows that the new approach is robust for diagnosing the machine tool spindle condition.
